摘　　要：延长网络生存期、减少网络能量消耗是传感器网络一项重要性能指标,分簇方案是实现该目标的主要方法之一。引入了传感器节点检测半径的概念,在分簇算法的基础上提出一种能量优化策略,该策略通过减少网络中处于激活状态节点的个数,减少网络消耗能量,延长网络的生存期。最后通过对典型的分簇算法LEACH应用该优化策略,仿真结果表明能量优化策略能显著的减少网络的能量消耗。Prolonged network lifetime is one of important requirements for many Ad Hoc sensor network applications. Clustering scheme is an effective technique to achieve this goal. The conception of sensing radius is introduced and an energy-efficient algorithm is presented based on clustering schemes which save energy and prolong the network lifetime by reducing the number of active nodes. Simulation results demonstrate that our scheme which is optimized on the basis of leach saves much more energy.
