摘　　要：能量优化是无线传感器网络研究中最重要的问题之一。在研究多跳通信中,平衡传输能耗和接收能耗,从而在最小化通信总能耗的基础上,引入最优通信范围。然后,提出一种基于次优距离的多跳路由算法。该算法基于次优距离在局部圆中随机选取传感器结点作为中转结点,保证了在最优通信范围附近选取中转结点。仿真结果验证了该算法有效地节省了网络能量,提高了网络生存期。In the wireless sensor networks, saving energy is an important aim. It introduces an optimum radio range, considering the balance between the transmission energy consumption and the receiving energy consumption to minimize the energy consumption in multi-hop communication. Then a sub-optimal distance based multi-hop routing algorithm is proposed, in which the relay is selected randomly in a local circle. Thus, the sensor nodes near the optimum radio range are selected as the relays. Simulations show that the algorithm can save more energy and prolong the network lifetime.
