Target tracking in WSN

  Sensors can be widely deployed within a geographic area in order to gather physical data (e.g., sound and temperature) and to facilitate efficient and collaborative control of various natural and human like events. One interesting application of wireless sensor networks (WSN) is target tracking in a hostile environment, where physical access is accompanied by some form of danger, i.e. the battlefield. My research interest focuses on the moving vehicle localization and tracking in wireless sensor networks and use multi-hop transmission for communicating alerts generated by sensor nodes to special control nodes or base stations.

Routing in VANET

  Unlike other wireless ad-hoc networks, e.g. sensor networks, several issues are important in the design of VANET routing protocols.
1.Dynamic and rapidly changing topologies of vehicular networks can cause frequent communication disconnections among vehicles.
2.Geographic forwarding selects the shortest route (minimal number of hops) that may suffer from a higher packet error rate due to the poor link quality of each hop.
3.The uneven distribution of vehicles on the roads makes route selection more complex, e.g., the shortest path in terms of geographic distance may experience more frequent network disconnections.
4.Some protocols such as VADD and CAR make use of the density information on roads to select routes; however, the inaccuracy of statistical data could cause route paths to be wrongly computed.
My research interest is to design and develope the efficient routing protocol for moving vehicles communications.
