This paper uses tabu algorithm to optimize the topology and puts forward the methods which is choosing topology reconstruction is involved in all nodes or directly to connect the surviving nodes before and after death node on the chain according to whether death nodes is on the long chain
in the event of node dies.At the same time
when cluster leader is choosing
the paper presents a algorithm which is comprehensive consider that the energy consumption of minimum residual energy nodes in the next round
residual energy of nodes and the distance to base station
in data transmission phase
compares the distance of the nodes to the next hop node with the distance of the node to the cluster head nodes
chooses the shorter path.Simulation results show that the lifetime of the first dead node is more than 4.9times of such node in PEGASIS
the death time of half of the nodes is also longer
so as to improve the survival time of the whole network.
