Development of a New Routing Protocol Based on GPSR for Wireless Sensor Networks

GPSR routing protocol is incapable of controlling the energy consumption of single node, causing network monitoring loophole. In the current study, a new routing algorithm NEWGPSR was developed from by original GPSR protocol with the introduction of LEACH clustering thought and the improvement of its head selection algorithm, appending active excitation mode, the heuristic rules and local optimization strategy, improving surrounding forward mode.Results of simulation analysis using NS3 platform showed that the new NEWGPSR algorithm was capable of effectively reducing system energy consumption, prolonging the network life cycle, and improving the performance of the entire network.
