【摘要】 为解决广播给无线多跳网络带来的严重的资源竞争与冲突、过大的转播冗余与能耗的问题,提出无线多跳网络有效广播机制.以获取高广播效率为目的建立了最佳转播模型,基于最佳位置转播和平衡能耗的思想来减小转播次数和能量消耗.该广播机制仅需本地信息就可完成有效转播,理论分析与仿真研究表明该广播策略是一种分布式、低开销、低转播冗余的无线多跳网络"绿色"广播机制.更多还原

【Abstract】 To solve problems such as serious packets collision,bandwidth waste,broadcast redundancy,and battery energy exhaustion,which are induced by broadcasting in wireless multihop networks,an efficient broadcast mechanism is presented in this paper.Optimized rebroadcast model is established to obtain high efficiency for broadcasting.It optimizes broadcasting by reducing redundant rebroadcasts and balancing the energy consumption among all nodes.Only local information is required to complete efficient broadcast.Theoretical analysis and simulation results show that it is a‘green’distributed broadcast mechanism with low overhead and low redundancy for wireless multi-hop networks.更多还原
