Possible Research Topics (but not limited to)

Wireless Ad Hoc and Sensor Networks

A wireless sensor network is a wireless network consisting of spatially distributed nodes with limited resources that can cooperatively monitor physical or environmental conditions at different locations. Each node is capable of computation, sensing, and communication. Challenges may be exacerbated by the presence of mobile nodes in the network. Such networks may consist of independent and isolated fixed devices that gather environmental data, which may be embedded in urban environments in order to facilitate actuation over managed resources, or may be fixed to and move with the object of interest. Ad hoc networks may exist in environments where there is no pre-existing communications infrastructure, and thereby organize to create their own. Ad hoc networks have been attracting great attention from the research and engineering communities, motivated by applications like digital battlefield, asset tracking, air-borne safety, situational awareness, and border protection. As we move towards a world that connects all things, these issues become ever more relevant. Dynamic topologies, bandwidth constraints, energy constrained operations, wireless vulnerabilities, and limited physical security are among the characteristics that differentiate mobile ad hoc networks from fixed multi-hop networks.
