摘要
无线传感器网络以其对恶劣环境良好的适应性、部署的简单性,被认为将成为未来火星探测的重要手段之一。然而,工作在火星这种恶劣的自然环境下的无线传感器网络往往具有带宽与路由的时变性,当网络负载严重或者网络中存在贪婪用户流量时,网络端到端的吞吐量和时延产生不稳定,导致网络性能下降。采用微分博弈理论及其反馈Nash均衡解的有效性,建立动态流量分配及动态QoS路由模型,获得非合作条件下流量分配的反馈Nash均衡解析解,进而提出动态QoS路由算法。仿真结果验证了所构造的动态QoS路由算法的可行性与有效性。
Wireless sensor networks(WSN) are considered to be one of the most important means to the future exploration of mars.The wireless sensor networks working in mars harsh natural environment often have the characteristics of multiple links,severe networks loads and a large number of non-cooperative users with throughput and delay unsteadiness.So,a QoS routing algorithm was introduced based on the differential game and Nash equilibrium solution which is feasible and effective through simulation.
