摘　　要： 通过从外界获取太阳能,传感器网络节点的能量限制得到缓解。提出一种太阳能传感器网络的自适应休眠调度算法。当观测场景从区域观测到目标跟踪转变时,节点自适应地转换活跃和休眠状态,同时剩余能量低于能量阈值的休眠节点从外界获取太阳能。与不考虑太阳能获取的休眠调度算法相比,提出的算法延长了网络生命周期。 Through harvesting solar energy, energy limitation of nodes in sensor networks is relaxed. An adaptive sleep scheduling algorithm is proposed for solar energy harvesting sensor networks. When the monitoring scenario varies from area surveillance to target tracking, node adaptively changes its status between active and sleeping. Meanwhile, sleeping nodes whose residual energy are less than energy threshold harvest solar energy. Compared with the sleep scheduling algorithm without considering solar energy harvesting, the proposed algorithm can extend network lifetime.
