摘　　要：提出了一种新的支持移动Sink的多媒体传感器网络路由协议,该协议利用锚节点作为转发节点与移动Sink进行通信,避免多媒体传感器节点与Sink直接进行远距离通信,在多媒体传感器节点中采用改进的基于地理信息的路由协议建立路由路径。仿真实验表明:该协议不仅能支持移动Sink,而且能够有效降低节点能耗,延长网络寿命,提高数据传输效率。A new protocol for mobile Sink in multimedia sensor network routing is proposed.The protocol uses anchor nodes as forwarding node to communicate with the mobile Sink so that direct long-distance communications for multimedia sensor nodes and Sink can be avoided.Sensor nodes in the multi-media uses an improved geographic greedy forwarding routing protocol to establish the routing path.Simulation results show that the agreement will not only support the mobile Sink,but also support nodes to reduce energy consumption,extend the network lifetime and improve the efficiency of data transmission.
