PWDGR: Pair-Wise Directional Geographical Routing Based on Wireless Sensor Network

摘要: Multipath routing in wireless multimedia sensor network makes it possible to transfer data simultaneously so as reduce delay and congestion is worth researching. However, the current multipath strategy may cause problem that node energy near sink becomes obviously higher than other nodes which invalid dead. It also has serious impact on performance of (WMSN). In this paper, we propose a pair-wise directional geographical (PWDGR) solve bottleneck problem. First, source can send around accordance with certain algorithm then will node. These are equally selected 360° scope according algorithm. Therefore, effectively relieve burden Sink make balance between consumption end-to-end delay. Theoretical analysis lot simulation experiments PWDGR have been done results indicate superior proposed strategies similar both view theory those experiments. With respect same kind, able prolong 70% life. The time measured only increased by 8.1% compared strategies.
