    • Objective: The goal of the present project is to explore an unexplored yet unique aspect of smart environments. It intends to study how smart physical environments can be further augmented with real-time signals or information coming from various other sources or channels that are integral parts of modern life to derive rich insights for predictive and prescriptive intelligence. These additional sources may include sensor signals coming from human wearable sensors as well as social sensors. Social sensor signals are derived from time-stamped text generated by humans and may include all permissible content generated in the form of emails, social media posts, News etc. While environment sensors provide information about the physical state of the space, social signals provide information about the physiological and mental states of the inhabitants. These signals also provide individual and collective behavioral cues about the social group that inhabits a space at a given point in time – thereby making them richer sources for insight generation. While each of these sources have been studied in isolation, a holistic approach to build a fusion framework for amalgamating signals or insights from a plethora of complementary and supplementary sources to obtain causal patterns among them have not been taken up earlier. We intend to explore the inter-relationships among different types of signals received through different channels to understand their spatio-temporal and behavioral correlations as well as infer causal associations, if any. Such explorations can not only potentially unravel novel knowledge about human behavior in different types of social settings but also lead to the design of wireless sensor networks imbibed with cognitive capabilities and activity context awareness, which in turn can be used for designing intelligent living spaces with predictive capabilities.

    • Objective: There has been phenomenal growth in web traffic over the personal Internet of Things (IoT) hubs in the recent years. In this project, we plan to study the nature of traffic generated by various smart mobile devices that contribute towards a personal IoT hub. We have observed that apps generate traffic with well-defined patterns. These patterns are evident in the distribution of packet-level characteristics (such as packet size, inter-arrival time), burst-level characteristics (such as burst size, inter-burst arrival time, etc.) and timing characteristics, which can be exploited to distinguish between traffic flows generated by different apps. The aim of the project is to design services to (i) segregate traffic flows originating from various apps inside a personal IoT hub, by analyzing their traffic patterns and (ii) predict QoS and QoE requirement of users in real-time. The deliverables of this project include systems to (i) enable service differentiation for network administrators of private networks, and (ii) implement video QoE adaptive streaming for content servers.

    • Objective: The Internet of Things (IoT) refers to uniquely addressable objects and their virtual representations in an Internet-like structure. The basic idea of this concept is the pervasive presence around us of a variety of things or objects – such as Radio-Frequency Identification (RFID) tags, sensors, actuators, mobile phones, etc. – which, through unique addressing schemes, are able to interact with each other and cooperate with their neighbors to reach common goals. While technology experts have anticipated a world of smart, connected device for decades, with cheaper hardware, advanced software, processing power offered by cloud computing as well an enhanced connectivity, IoT is at an inflection today.

      According to McKinsey Global Institute, the Internet of Things has the potential to create economic impact of $2.7 trillion to $6.2 trillion annually by 2025. That creates a mammoth opportunity for India. While there are a lot of opportunities as well as industry demand, the existing engineering curriculum does not cover the requirements. This also has implications on the new entrants, who have not been exposed to the various IoT modules. This proposal aims to cover this gap by setting up a Teaching Learning Centre (TLC) for Internet-of- Things. The center will put its main focus on the thrust areas such as
      1. IoT for Healthcare, Agriculture, Water, Security and Safety
      2. IoT for Smart-Grid and Smart-Building
      3. IoT for autonomous mobile robots and tele-operation of multi-agent systems
      4. Social Internet-of- Things
      5. Big Data Analytics for IoT

      The center would work towards building research-oriented course content for these thrust areas. The main objectives of this center can be enumerated as follows:
      1. To develop a curricular framework for IoT to be used by colleges and post-graduate departments
      2. To develop learning materials, repositories of resources including open-source software and platforms, electronic database
      3. To provide recommendations towards pedagogy and assessment scheme for the IoT curriculum
      4. To conduct rigorous pre-induction programs or the new entrants and in-service faculties and to promote research and critical thinking through project-based learning
      5. To develop state-of- the-art lab facilities for the thrust areas to provide hands-on for the new entrants

    • Title: WiHi: High Speed Wireless Access with Network Resilience and Improved User Experience
    • Sponsor: SRIC, IIT Kharagpur (Under ISIRD)
    • Amount: 27.35 Lakhs
    • Duration: 3 Years (2015-2018)
    • Principal Investigator: Sandip Chakraborty
    • Objective: The next generation Internet architecture is gradually shifting from fixed communication layouts to mobile and dynamic communication entities, along with a coherent changes in application traffic pattern. In line of this, the design, development and planning for future “connected cities” demand high speed wireless backbone networks for community usage as well as for metropolitan area communications, so that extensive supports for seamless mobility across the network become prominent. Although the designs of high speed communication and Gigabit wireless technologies are in pace, recent studies shown that there are significant coordination gaps among the lower layer high speed communication technologies and the upper layer protocol principles. This leads to a non-optimal usage of communication resources, like bandwidth and network capacity, and significantly affects end-user experience. The objective of this project is to design, develop and implement a high speed wireless access network that supports network resilience and better end-user experience in terms of quality-of-service (QoS) and quality-of-experience (QoE). In this project, our first objective is to develop a prototype testbed for high speed wireless access along with a controllable software defined radio (SDR) platform, and then analyze the effect of physical (PHY) and medium access control (MAC) parameter settings over the upper layer protocol performance. This analysis is non-trivial and significantly differs from the existing studies because of the emerging traffic behaviors at the next generation dense access networks. Based on this analysis, we aim to design a set of coordination protocols at MAC and transport layers, with a special focus on end-to-end semantics for network resilience and application layer QoS. Finally, we aim to implement the advanced protocols over the testbed, and analyze their performance in real network scenarios.

    • Title: QoS based Network Resource Management to Cater to Dynamic Workload Mobility in Hyperconverged Architecture
    • Sponsor: Hewlett Packard (India) Software Operations Private Limited
    • Amount: 14.40 Lakhs
    • Duration: 01 Year 06 Months (2016-2018)
    • Principal Investigator: Prof. Sandip Chakraborty
    • Co-Principal Investigators: Prof. Niloy Ganguly
    • Objective:Current Hyperconverged (HC) environments are predominantly used for workloads such as VDI. However, HC architecture is set to evolve towards support for diverse enterprise applications with varying workload characteristics and associated scalability. This consequentially drives workload mobility requirements for optimal application workload placement on the HC nodes for efficient resource utilization, or workload migration for Business Continuity. Workload mobility is a key requirement in Data Centers for optimal workload placement and Business Continuity. Mobility of workloads, exemplarily VMs, can broadly cover (1) live migration of workloads, and (2) mobility triggered for optimal workload placement for efficient resource use For meeting the above requirements, dynamic resource management in hyper-convergence architecture, considering application performance and QoS simultaneously, is a challenging task. As new or varying intensity workloads demand for resources based on their service level agreements (SLA), the task is to optimally redistribute and schedule the resources with minimal impact over the performance of existing systems.

    • Title: Design and Development of Activity/Event Based Authentication Framework
    • Sponsor: Bharat Electronics Ltd. (A Govt. of India Enterprise) Central Research Laboratory,Jalahalli Post, Bangalore - 560 013
    • Amount: 10.00 Lakhs
    • Duration: 01 Year (2016-2017)
    • Principal Investigator: Prof. Niloy Ganguly
    • Co-Principal Investigators: Prof. Bivas Mitra, Prof. Sandip Chakraborty
    • Objective:Daily individual, group activities of people and events occurred in computing elements (like Desktop Computer, Laptop and Mobile phone) can carry a unique signature and is known to the users of the system only. Hence these signatures can be utilized to allow a person or device to get authenticated to the network or the application. In this project, our aim is to capture the activities and exploit these activities to propose an authentication scheme. This innovative authentication scheme will generate challenges related to user’s individual or appointment based group activities. This authentication method can be implemented for individual users and for group of users. Group activity is a complex function of activities that all the individuals in that group perform. The proposed authentication scheme generates challenge questions based on activities performed in the computing system by individual users and the challenges are dynamic by nature. The mobile phone activities include phone activities (call, sms etc.), web browsing, OSN activities and Desktop computers and Laptops activities include browsing, access of different applications and application logs and events. This novel authentication scheme will be an additional factor authentication along with the regular password/ passphrase based authentication. The proposed method can replace biometric (fingerprint, Iris) based authentication where it is difficult to use to provide 2 factor authentication. The proposed method is more secure because the challenges posed for authentication are dynamic and correct response is known to the user only. The proposed system is expected to be more scalable than biometric based systems.
