一种节省能量的水声传感器网络组织结构与协议

An energy-efficient framework and protocol for underwater acoustic sensor networks

本文为水声传感器网络提出了一种基于簇间协商的事件报告策略,网络节点以簇的形式组织起来,多址接入协议采用了一种适合水声环境的TDMA/CDMA混合式协议,建立了由簇头与网关组成的用于簇间通信的主干链路。仿真结果表明,基于簇间协商的事件报告策略能有效减少网络中的冗余通信量从而延长网络寿命。

In the paper, an energy-efficient events reporting scheme relied on inter-clusters negotiation for underwater acoustic sensor networks is proposed. In this theme, nodes are grouped into clusters, TDMA/CDMA hybrid multiple access protocol is used, and inter-cluster communication backbone is built, which includes cluster-head and gateway. Simulation results show that the proposed scheme could reduce the redundant traffic and increase the network lifetime efficiently.
