A Routing Algorithm Based on the Characteristic of Complex Network for Wireless Sensor Network
In wireless sensor networks where nodes operate on limited battery energy,some other unique characteristics make these nodes impossible to be replaced or recharged.The sensor nodes are facing the random failure and the selective attack all the time because the nodes are disabled easily.Thus it will cause partial or entire network disintegrating.We have analyzed .the common three kind of wireless sensor network topology and overall considered routing thought of flooding algorithm and LEACH algorithm,then proposed a new routing algorithm based on the characteristic of complex network.In the algorithm the threshold function is used to control that numbers of few nodesload grow excessively quickly.This is helpful in enhancing the network invulnerability. Finally the network performance analysis and the simulation result indicated that it can improve network robustness and invulnerability after applying this algorithm in the wireless sensor network.
