Post-Disaster Communications

In the event of a large-scale disaster, natural (e.g., earthquake) or man-made (e.g., terrorist attacks), a communication infrastructure is essential for prompt rescue and relief operations. However, the partial (or complete) impairment of primary communication and power infrastructures makes it difficult for the responders to assess the required logistics for recovery efforts, identify and extend rescue/relief to the survivors. In this research, we focus on designing novel architectures and protocols for establishing reliable and energy-efficient communication networks, termed Disaster Response Networks ; to enable information exchange between survivors and responders (until the primary infrastructures are not restored).

Smart and Connected Communities

Ubiquitous connectivity is a crucial requirement for future smart and connected communities (SCCs), whether rural, sub-urban or urban. Such connectivity enables to gather, disseminate, and analyze information on multiple sensing modalities, for efficient decision making of several frontiers of human life. To form such SCCs, huge communication infrastructure is needed to offload data from millions of physical sensors blocks to their respective decision making units (e.g., data center) usually within certain time deadlines. However, realization of such huge communication infrastructure faces serious economic and sustainability hurdles, particularly in rural and sub-urban areas. Hence in this research, we aim to propose an easy-to-deploy, low-cost and sustainable alternative option for providing connectivity in rural and sub-urban areas.

Trust Models in Participatory Sensing

Sophistication in mobile devices (e.g., smartphones, tablets) and their widespread adoption have given rise to a novel inter-active sensing paradigm, known as Participatory Sensing (PS). Due to the concept of `gamification' , several selfish behaviors are possible, while the potential civilian impact of a security breach may motivate malicious intent. Wrong perception or noisy measurements further affect the reliability, dependability and trustworthiness of user's, data and services. This project aims to solve the above challenges using behavioral theoretic approaches and decision theory for achieving secure and trustworthy PS systems.
