Topology Control of Wireless Sensor Networks Under an Average Degree Constraint
Chen Li · Chinese Journal of Computers · 2007
Topology control is one of the most important technologies in wireless sensor networks. In the precondition of the topology connectivity of wireless sensor networks, how to solve the sparseness of the network topology is a very important problem in a large number of sensor nodes deployed randomly. Existing topology control schemes show that network topology is complex and routing process consumes the resources heavily. This paper presents the topology control of wireless sensor networks under an average degree constraint. With increasing communication radius and constraining node degree, the inconsistency of network topology connectivity and sparseness can be solved. The simulation and analysis study demonstrate that proposed scheme can decrease working nodes, guarantee network topology sparseness, predigest routing complexity and prolong network survival period.
