Abstract


The wireless sensor network (WSN), which is integration of sensor techniques, computer science and technology, signal processing, network communication, is a cross-disciplinary subject. In some special fields, it has become a new hotspot, for its wide application in recent years.Wireless sensor network consists of many sensor nodes, which their energy is non-renewable, they collect and process information collaborative, and send the information to the base station through self-organization, multi-hop communications. In order to prolong its life cycle effectively, it require to design a more concise rule. Wireless sensor network routing protocol is one of the core technology, which sent from the source node to destination node key tasks. It has become the focus research of many scholars.The paper introduces the ETBG (energy-aware topology control protocol based on gradient) algorithm and propose its maintenance and update algorithm in the light of Topology changes caused by new nodes join or nodes death. One important thing which is distance has not been considered in the course of the cluster head choosing, it can make much more energy consumption and lead to shortened the network life cycles, so the paper make a balance between energy and distance in the course of the cluster head choosing. In addition, in order to solve the problem which the cluster head is much more density, we have the same gradient nodes chose the cluster header and reference to the Strategy of EAHC-G in the course of cluster-tree building. The method can make the number of cluster header more reasonable and prolong the network life cycle.
