Transition-Zone-Based Greedy Forwarding Strategies for Mobile Wireless Sensor Networks
Ling Wang · Chuangan jishu xuebao · 2007
On the basis of analyzing the phenomenon of temporary communication blindness resulted from period beacon exchange adopted by Greedy Forwarding Strategies(GFS) in mobile wireless sensor networks(MWSN),a new transition-zone-based greedy forwarding strategies(TZGFS) is proposed.The key idea is that forwarding node selects the neighbor node whose distance to sink node is the least and less than himself in the radio range excluding transition zone.Simulation shows that the routing that uses TZGFS can acquire high reachrate(data transfer success ratio)for eliminating the phenomenon of temporary communication blindness,so TZGFS can be adopted by greedy geometric routing protocol for large-scale reliable MWSN.
