In order to ensure the QoS requirements in routing discovery as much as possible,this paper introduces a probability transmit mechanism to select the next hop node in the forward region.The traditional Geographic Perimeter Stateless Routing(GPSR)algorithms can be improved for WSN.This new algorithm is proposed and named Improved Geographic Perimeter Stateless Routing(IGPSR).There are mainly two differences in the new IGPSR algorithms compared to the traditional GPSR algorithms:(1)IGPSR algorithms divide the forward region into different segments according to the residual energy of the neighboring node;(2)it adopts the probability transport mechanism to select the next hop node in the segment of the chosen forward region.The simulation results show that the IGPSR algorithms work more effectively than the traditional GPSR algorithms in balancing the energy consumption and prolonging the lifetime of the network.
