摘要
认知无线传感器网络的广播及其可靠传播问题引起了许多研究者的关注。广播是网络的重要功能,广播策略的性能会影响认知无线传感器网络的数据传输;提高广播重传的效率、解决重传冲突问题是保障广播有效性的手段。首先通过分析主用户的行为,设计了基于主用户行为的广播策略。然后,针对广播重传以及冲突问题,设计了基于潜博弈的重传策略。最后,在仿真平台上实现这两种策略,并与现有的策略进行对比,评估本研究策略的性能。
Broadcasting and its reliability in cognitive radio sensor networks has attracted the attention of researchers. Broadcasting is an important function of network. The performance of the broadcast strategy will affect the data transmission of the cognitive radio sensor network. Increasing the efficiency of broadcast retransmission and solving retransmission collision are the means to ensure broadcast effectiveness. This paper first analyzes the behavior of the primary user and designs a broadcast strategy based on the activity of primary user. Then, based on the broadcast retransmission and collision problems, a retransmission strategy based on the potential game is designed. Finally, these two strategies are implemented on the simulation platform and compared with the existing strategies to evaluate the performance of these strategies.
