A Range Of Sub-clusters Based On The Geographical Location Of The Wireless Sensor Network Routing Protocol

Wireless sensor networsk(WSN) integrate sensor technology, embedded computation,distributed information processing and wireless radio communication technology.It can collaborate to monito,collect and process all kinds of information about the monitor object.How to prolong the lifetime of WSN is primarily concerned when design WSN routing protocols.In this paper,We first discuss cluster-based routing protocol,and then we analyze Low Energy Adaptive Clustering Hierarchy(LEACH) protocol.We present a routing protocol based on geographic location hierarchy clustering GCRP.The algorithm first determine the optimal monitoring of regional cluster number of the first node,and then adjust the size of the radius divided by region under the node distance from the Sink node cluster.Covers the regionalism certain area not equal bunch the network,and guaranteed that in each bunch has a bunch of first node,solves in the LEACH agreement a bunch of first integer and the distribution unstable question,the bunch uses Shan Tiaohuo to jump the correspondence.At the same time,we to LEACH in valve value T(n) the computational method makes the improvement,avoided in LEACH the excess energy few nodes becoming the bunch of head's question.And we simulate the new protocol and LEACH on on my own simulation platform. The simulation result show that the new protocol saves the energy of the whole network and balanced the energy consumption of nodes,therefore prolong the lifetime and improve the performance of the network.Finally,We conclude the main work of the thesis and propose some problems that need to study in future.
