摘　　要：针对采用多跳传输数据时靠近基站的节点易耗尽能量而失效、单跳传输数据时距离基站较远的节点很快失效的问题,提出了"2跳"的概念和基于时分的路由算法,其基本思想是在不同时间段分别采用单跳、多跳和"2跳"路由。仿真实验表明,算法使节点能量消耗比较均匀,能延长网络的生命周期。One of the most challenges is to extend the network lifetime in wireless sensor network under the condition that sensed data is able to be delivered to the Sink. Existing solutions of routing algorithms include multi-hop and one-hop. Multi-hop leads to earlier failure of the nodes nearby the Sink because of heavy energy consumption, while one-hop leads to earlier failure of the nodes which is far away the Sink. Motivated by these reasons above, a new concept of two-hop and a routing algorithm are based on time division. The main idea of this algorithm is that one-hop, multi-hop and two-hop are used in different time slices. Experimental simulations prove that the algorithm is more energy-efficient to prolong the network lifetime.
