中文摘要：
针对间歇性连通的移动无线传感网提出一种能量时延约束的自适应路由协议（EDcA），EDCA由初始化阶段、转发决策阶段、转发阶段和等待阶段组成，传感器节点根据目标时延实时判断是否转发副本，并选择剩余能量多的节点进行副本转发．EDCA对平均时延和网络负载具有控制力，对网络环境变化具有自适应能力，能够有效延长网络生命周期．
英文摘要：
An energy-delay-conslraint adaptive routing（EDCA） is proposed for intermittently connected mobile wireless sen- sor networks （MWSN）, which includes initialization-phase, Iransfer-judging-phase, flooding-transfer phase and waiting phase, and in which sensor nodes judging whether to transfer message copy or wait to meet the destination node according to target delay and judging which one to transfer message copy according to remain energy. Simulation results show that EDCA is an efficient delay bounded and network load bounded routing scheme, and can adjust the number of message copy adaptively according to target delay when network environment changes, and can balance the energy consumption of sensor nodes and prolong the network lifetime.
