【摘要】：传统的无线通信网络由于结构单一,性能上诸多受限,难以保障应急通信的质量。为此,在认知无线自组织网络与移动蜂窝网络相融合的新背景下,提出一种多路径Bandit算法。将通信中的选路过程分为多时隙路径选择子阶段,通过对权衡网络时延和能效目标函数的计算进行路径优选,从而合理地分布网络中各节点的能耗。仿真结果表明,对比非应急业务应用和贪婪算法,在融合网络应急业务应用下,多路径Bandit算法的网络生存期提高了3%~20%。
[Abstract]:The traditional wireless communication network is difficult to guarantee the quality of emergency communication because of its single structure and limited performance. Therefore, under the new background of cognitive wireless ad hoc network and mobile cellular network, it is difficult to guarantee the quality of emergency communication. In this paper, a multipath Bandit algorithm is proposed. The routing process in communication is divided into the sub-stage of multi-slot path selection, and the path optimization is carried out by calculating the tradeoff between the network delay and the energy efficiency objective function. The simulation results show that compared with the non-emergency service and greedy algorithm, the multipath Bandit algorithm can improve the network lifetime by 30% in the case of fusion network emergency service application, and the simulation results show that compared with the non-emergency service application and the greedy algorithm, the network lifetime of the multi-path Bandit algorithm is improved by 30%.
