摘　　要：针对WSN位置路由算法中的距离和角度选取问题,本文研究了四种组合选取策略,并通过NS2仿真进行验证。结果表明:综合考虑角度和距离选取策略优于单一考虑角度或距离选取策略;对节点数较少的网络,采用先角度后距离策略;对节点数较多的网络,采用先距离后角度策略,更能有效地提高WSN网络能量有效性。The four combination selection strategies were researched in this paper, aiming at the selection problem of the WSN geographic routing, which was verified by NS2 simulator. The results of simulation show that the integration of the angle and distance selection strategy is better than the sole distance or angle selection strategy, and the energy efficiency of the WSN is improved highly by using the strategy of first angle then distance in less nodes network and first distance then angle in much nodes network.
