摘　　要：移动Ad Hoc无线网络节点在广播报文信息时占用大量的网络资源,且广播信息的能量开销较大。为了解决这些问题,提出一种基于自适应选择gossiping概率的多跳网络数据广播协议。该协议首先基于网络节点密度分布情况及节点平均邻居数量来定义gossiping概率,减少广播信息的开销,再为自适应gossiping概率加入选择能力,从候选邻居节点中排除会带来传输中断情况的节点,避免能量损失。实验仿真结果表明,该协议相比较gossiping路由协议、传输感知的机会Ad Hoc路由协议和轻量级的移动Ad Hoc网络主动源路由协议,网络总能耗分别减少了32.5%、14.6%和2.1%,并且在降低数据包丢失率和减少数据包传输延迟上表现出较好的效果。Mobile Ad Hoc wireless network nodes took up a lot of network resources and the energy cost of the larger broadcast information in the broadcast packet information. To solve these problems, a multi- hop network data broadcast protocol based on adaptive selection gossiping probabilistic is proposed. The protocol defines the gossiping probability based on the number of network nodes and node density distribution of the average neighbor, to reduce the cost of the broadcast information. It adds the ability to select an adaptive gossiping probability, and excludes the nodes will bring node transmission interruption from the candidate neighbor nodes. Simulation results show that compared with gossiping routing protocols, perceived opportunities transmission Ad Hoc routing protocols and lightweight mobile Ad Hoc network active source routing protocols, the network total energy consumption decreases by 32. 5 %, 14. 6 % and 2. 1 %, and can reduce packet loss rate and reduce packet transmission delay well.
