摘　　要：应急通信网是一种无线自组织网络,用于灾害过后的快速通信保障。广播是应急通信网络不可缺少的路由技术,传统的概率广播无法兼顾网络传输的可靠性和有效性,为了解决两者之间的矛盾,提出一种高效的加权概率广播算法,通过引入加权系数和目标函数取得两者的折中。大量仿真实验得到了各种网络配置下的最优广播概率,实验结果表明,所提出的加权广播算法以很小的可靠性损失换取很大的有效性增益,大大提升了应急通信网的工作效率。Emergency network is a type of ad hoc networks.It could be used for prompt communication provision for disaster.Broadcasting is an indispensable routing technology for emergency networks,but the traditional probabilistic broadcasting cannot reconcile reliability and efficiency of network transmission.To solve this problem,an efficient weighted probabilistic broadcasting algorithm is proposed to obtain a compromise between the two by introducing weighting coefficients and objective functions.The optimal broadcasting probability under various network configurations is obtained by extensive simulation experiments,and the results show that the proposed weighted broadcasting algorithm could achieve significant efficiency benefit with a little cost of reliability loss,so as to improve the efficiency for emergency networks greatly.
