基于最小跳数的无线传感器网络路由协议

Routing Protocol for Wireless Sensor Networks Based on Least Hop

高效地实现路由转发是无线传感器网络路由设计的一个关键点。该文在现有基于簇的分层路由机制的基础上,提出一种基于最小跳数的路由转发模式,其核心是在建立的簇中采用最小跳数路由算法。该算法简单、易扩展,簇内节点只要记忆各自一跳范围内的转发节点集,就能沿最短路径向簇首发送数据。仿真结果表明,该模式节能效果较好,延长了网络寿命。

How to realize routing transmit efficiently is a key issue in network routing design. Based on the current cluster-based delamination routing mechanism, this paper proposes a routing transmit model, in which least-hop arithmetic is used in the built clusters. This arithmetic is easy and extensible. The nodes in the clusters can remember the transmitting nodes sets within one hop bound to transfer data to the head of cluster along shortcut. Simulation results show that it has better power saving performance and can prolong the lifetime of the network.
