摘　　要：针对无线传感器网络能量有效性问题,提出一种新的WSN路由算法ACPR。算法采用无线蜂窝网覆盖思想,使用角度比和距离比选取转发节点,并采取角度优先策略。通过NS2仿真验证,结果表明,在减少转发节点数和网络冲突次数上,综合考虑角度和距离信息选取转发节点策略优于距离选取策略,而且与DD和Activecast路由算法相比,ACPR算法提高了能量有效性。A new WSN routing algorithm ACPR is proposed aiming at the problem of the energy efficiency in wireless sensor networks. Based on the covering idea of the wireless cellular networks, the forwarding nodes are selected by the angle ratio and the distance ratio giving priority to the angle, which is verified by NS2 simulator. The result of simulation shows that the integration of the angle and distance selection strategy is better than the distance strategy in reducing the number of the forwarding nodes and the network collisions, and the ACPR algorithm improves energy efficiency compared with the DD and Activecast routing algorithms.
