摘要
移动自组网(MANET)因其灵活的组网方式在军事和传感器网络领域得到广泛的应用,但是由于MANET的固有特征,网络节点之间的通信通过无线传输来完成,节点的发射功率、能量以及通信信道均受到限制,使得MANET信息传输的可靠性和安全性难以得到很好的保障。为提高网络通信的稳定性,利用移动自组网路由协议的基础上,针对网络通信可靠性的具体要求,分析了路由策略需要考虑的多种因素,提出基于跨层设计的移动自组网多安全等级路由策略。仿真结果表明,路由策略保证了网络通信可靠性,并比传统单一条件的路由选择策略更合理地利用网络资源,平衡流量负载,减少网络传输延迟,延长网络使用寿命,提高转发效率。
Mobile Ad-hoc Networks （MANET） are widely used for its flexible structure in military and sensor networks field. But due to the inherent characteristics of MANET,the limited transmit power,energy of node and the restricted channel,the reliability and security have not been well solved. In this paper,we analyze and integrate three factors based on cross-layer design,and propose a multi-level MANET security routing strategy. The simulation results show the routing strategy in ensuring the reliability of network communication and comparing the traditional routing strategy,which can make rational use of network resources,balance the traffic load,reduce network transmission delay and prolong network lifetime.
