Topology Control Issues in Wireless Sensor Networks (wsn) for Intelligent Transportation Systems (its)

چکیده
Topology issues have received more and more consideration in Wireless Sensor Networks (WSN). While WSN applications are generally optimized by the given underlying network topology, another trend is to optimize WSN by means of topology control. A number of approaches have been identified in this area, such as topology directed routing, cooperating schemes, sensor coverage based topology control and network connectivity based topology control. A good number of the methods have proven to be able to offer an improved network topology for traffic monitoring and communication concert for intelligent transportation systems with extended system lifetime. In this paper, we present a full analysis of the studies in this area.
