TopDisc Algorithm for Topology Control Research Based on Dump Energy

Under the premise of ensuring the network connectivity and coverage, by selecting a good topology control mechanisms is good for improving the efficiency of network communication and prolonging the life cycle of network. Based on the analysis algorithms of TopDisc algorithm, this thesis introduces an improved algorithm of TopDisc-injecting the surplus of energy into the algorithm. And through analysis and comparison the two results, the conclusion comes: on the one hand, improved algorithm to draw the network on the survival time longer than the original algorithm; on the other hand, the nodes on the dump energy are more evenly than the original algorithm.
