摘　　要： 多媒体传感器网络面临的主要挑战是在能量受限的情况下传输大量数据。在经典分簇协议LEACH的基础上,提出一种考虑数据量的多媒体传感器网络低能耗分簇协议。在簇头选举阶段,选择剩余能量多和数据量大的节点作为簇头;在成簇阶段,同时考虑节点到簇头的通信距离和节点的数据量让节点加入簇。仿真结果表明,提出的协议能有效提高网络的生命周期。 The main challenge in multimedia sensor networks is the transmission of a large amount of data under the condition of the energy constraint. Based on the classical LEACH protocol, a low energy consumption clustering protocol of multimedia sensor networks is proposed in consideration of data quantity. In the cluster head election stage, the nodes that have more residual energy and more data are selected as cluster heads. In the cluster formation stage, each node joins a cluster depending on the communication distance between it and the corresponding cluster head as well as the data it holds. The simulation results show that this method can effectively prolong network lifetime.
