Energy-aware Diffusing Clustering Tree Routing Issues For Wireless Sensor Networks

The wireless sensor network (WSN), which is integration of sensor techniques, MEMS techniques and network communication techniques, is a new interdisciplinary branch of science. It uses huge amounts of nodes,that disseminate in the monitoring area,to monitor, apperceive and gather useful information. Now, the wireless sensor network has made great development in academia and application area, but there are also a lot of problems in need of solution.Beacause of the features of the wireless sensor network,the requirements of WSN's routing protocol are different with the traditional networks.So it needs to design some new routing protocol that accord the requirements of wireless sensor network, designing routing protocol has been a hotspot in the wireless sensor network.This paper analyses and compares the existing wireless sensor network routing protocol,at last introduces an energy-aware diffusing clustering tree(EDCT).The EDCT can builds a cluster-tree that has the least hops to the Base-station.lt chooses the maximal weights value nodes to be the cluster heads in parallel,that can avoid the low energy node premature death.Because of the energy -consume is pockety in the nerwork.,the ETBG use Mobile-Base-Station to balance the energy load and prolong the network lifetime.At last,this paper uses simulation to validate the EDCT arithmetic.When the sensor nodes turning on or off caused the change in hierarchical clustering tree, the problem we care is how to update this network rapidly and locally. In this paper, we propose the maintenance and update algorithm of the hierarchical clustering, making the EDCT algorithm scalable, self-recoverable, and more perfect.
