基于拓扑感知的水下传感网络路由

Topology–aware routing in underwater sensor networks

摘要:

由于水下传感网络的高时延、低带宽和高能耗等特性，建立路由协议仍存在挑战。为此，提出基于拓扑感知的水下传感网络路由(TAR)。TAR路由先通过交互Beacon包，使每个节点获取网络拓扑信息，并建立邻居信息表。再依据节点剩余能量和链路的可靠性，择优选择下一跳转发节点，进而提高路由的稳定性，平衡节点间能耗。仿真结果表明，提出的TAR路由增强了路由稳定性，并减少了节点的能耗。

Abstract:

It is challenging to build networking protocols for Underwater Sensor Networks(UWSNs) due to specific characteristics of UWSNs, such as high latency, low bandwidth, and high energy consumption. Therefore, Topology-Aware Routing(TAR) in Underwater Sensor Networks is proposed. TAR routing first makes each node obtain the network topology information through the interactive Beacon package, and establishes the neighbor information table. Then, based on the residual energy of the node and the reliability of the link, the next-hop forwarding node is selected to improve the stability of the route and balance the energy consumption among nodes. Simulation results show that the proposed TAR route enhances the routing stability and reduces the energy consumption of nodes.
