摘要
自组网中常用的洪泛路由协议采用全网节点转发方式,可能导致广播风暴,另一方面,无能量控制的广播会使某些剩余能量较少的节点快速失效。提出一种基于能量均衡的选择性洪泛路由算法EBSBA(Energy-Balance for Selective Broadcast Algorithm),根据邻居节点剩余能量多少动态调整传输范围,选择具有额外覆盖周长的邻居节点进行转发。仿真结果表明EBSBA算法可以有效地降低转发节点数,同时均衡节点的能量消耗。
Flood-routing protocol commonly used in Ad hoc adopts the whole-network nodes forwarding pattern, it may cause broadcast storm. On the other hand, the broadcast without energy control will cause some nodes with low residual energy to fail rapidly. We present an energy balance-based selective flood-routing algorithm EBSBA, it adjusts the transmission range dynamically according to the residual energy of the neighbour nodes, and selects neighbour nodes with additional coverage perimeter to forward. Simulation results show that the EBSBA can effectively reduce the number of forwarding nodes, and balances the node energy consumption simultaneously.
