Regional perimeter routing for GPSR based on left & right-hand rules
一种基于左、右手法则的GPSR分区边界转发路由协议*

To handle routing void problem of Greedy Geographic Routing Protocol in Wireless Sensor Networks, this paper analyzed shortages of methods which deal with the routing void, improved the Perimeter Forwarding strategy in GPSR, and proposed a Regional Perimeter Routing based on Right and Left-hand rules. The results of simulation indicate that the improved protocol can improve the Packet Delivery Success Rate, shorten Routing Path Length, and improve the Real-time Capability of Greedy Geographic Routing Protocol.
