摘要：

针对无线传感器网络能量有效性问题，提出一种基于传输半径倍数的交替路由算法(TSMAR). 算法计算出节点与信宿之间的距离，确定距离与传输半径的下整数倍数，然后根据倍数的奇偶性交替转发数据，同时抑制远离信宿或与发送节点距离较近的节点转发数据. NS仿真验证表明，与BPS算法相比，TSMAR算法减少了转发节点数，提高了网络能量有效性，延长了网络寿命.

Abstract:

We develop an alternant routing scheme aimed at energy efficiency of wireless sensor networks (WSN). The proposed method is based on the parity of transport radius multiples. The distance from the node to the sink is to calculate, then to make certain the lower integer multiple of the transport radius, the node forwards data alternately based on the parity of the multiples, and suppresses distant sinks and restricts data forwarding from nearby sending nodes. Network simulator (NS) simulation results show that, compared to the BPS algorithm, Alternant routing algorithm based on transport semi-diameter multiple (TSMAR) can lessen forwarding nodes, improve energy efficiency, and prolong the network lifetime.

Key words: wireless sensor networks, alternant forwarding, energy efficiency, network lifetime
