My research revolves around resource management, data management, security and handling attacks in wireless sensor networks, mobile ad hoc networks and cloud computing. The applications like border patrolling, monitoring chemical leakage, and troop’s movements in the battlefield require constant sensing capabilities using tiny sensors. In the Web and Wireless Computing Lab, I do have these small miniature devices called motes that can self organize themselves to create a wireless sensor network and can send data to a given base station. The problems of handling data, managing security and handling attacks are much more severe in this environment due to limitations on battery power [AA batteries], memory [128KB] and CPU speed [7Mhz]. So I work on designing light weight algorithms to handle data, provide secure passage of data to the base station and detect the presence of any malicious node in the path. I address issues like how to detect a malicious node which collects all data, but never forwards it, or forwards it to another part of the network or it will create fake identities. Also, a node can aggregate sensing data and may change the values like reporting the false number of troop’s movement, so the base station needs to verify that the reported data is correctly aggregated. My PhD and MS students have published several papers in the area of security and trust and build test-beds. I am also working on secure sensor cloud. More recently, I am working in the area of data integrity verification in cloud environment and we have designed protocols and implemented them in EC2 platforms. Some other areas where I have projects are secure Cyber Physical Systems, Mobile Cloud Computing and Sensor Data Fusion.
