Adjustable Topology Control Algorithm for Wireless Sensor Networks
In the topology control problem of wireless sensor networks,there is a tradeoff between keeping energy efficient paths and keeping low node degrees which depends on the specific applications and network dynamics. In this paper,a new topology control algorithm is proposed to adjust the topology between the two inconsistent goals. The constructed topology preserves all minimum energy paths at one extreme and keeps the average node degree close to the theoretical lower bound at the other extreme. The simulation results verify the ability of the new algorithm to preserve all minimum energy paths under more realistic power consumption model and shows that the new algorithm has larger node degree adjustment range compared to the existing approach.
