Under the promise of ensuring the network connectivity and coverage

by selecting a good topology control mechanism

the efficiency of network communication is improved and the life cycle of network is prolonged.Based on the analysis algorithms of TopDisc algorithm

an improved algorithm of TopDisc is introduced to inject the surplus of energy into the algorithm.Through the analysis and comparison of the two results

conclusion are drawn that on the one hand

the network survival time of improved algorithm is longer than the original algorithm.On the other hand

the dump energy of nodes by improved algorithm are more even than the original algorithm.
