摘要:
优化链路状态路由协议(OLSR)是移动自组织网络( MANET) 中使用十分广泛的路由技术,在网络中会通过定期地交互 HELLO 消息以获取节点邻居状态并感知与邻居之间的链路情况。 针对 OLSR 在易受干扰的战场信息网络中应用时,会使得节点在传输资源有限的情况下持续发送大量冗余 HELLO 信息,导致路由开销增大的问题,提出了一种基于节点静默-激活机制的优化链路状态路由( SA-OLSR) 协议。 该协议分为 HELLO 信息接收和发送两个模块,通过对节点最近一次接收到的 HELLO 包时间分析,感知当前节点所处的网络环境状况,判断节点是否需要进入静默状态,从而改变 HELLO 包的发送时间间隔,优化 HELLO 信息的发送频率。 该文使用 OPNET 搭设仿真平台,模拟出网络环境中遭受到干扰的情况,对 SA-OLSR,OLSR 以及现阶段 MANET 中常用的 AODV 协议进行了对比分析。 仿真结果表明,相比于传统的 OLSR,SA-OLSR 能够降低干扰网络中近 10% 的 HELLO 包控制开销、减小网络中出现长时期拥塞的概率;与 AODV 协议相比,SA-OLSR 的平均时延较低,且时延波动比较稳定。 同时能大大增加网络的吞吐量。
Abstract:
The Optimized Link State Routing ( OLSR) is a widely used routing technique in Mobile Ad Hoc Networks ( MANET) ,whereHELLO messages are exchanged regularly to obtain node neighbor status and perceive link conditions with neighbors. A novel optimizedlink state routing ( SA-OLSR) based on node silence activation mechanism is proposed to address the issue of OLSR being applied inbattlefield information networks that are prone to interference,causing nodes to continuously send a large amount of redundant HELLO information with limited transmission resources,resulting in increased routing overhead. This protocol is divided into two modules:HELLOinformation receiving and sending. By analyzing the time of the last HELLO packet received by the node,it perceives the current networkenvironment conditions of the node,determines whether the node needs to enter a silent state,and changes the sending time interval ofHELLO packets to optimize the sending frequency of HELLO information. We use OPNET to establish a simulation platform to simulateinterference in the network environment,and compare and analyze SA-OLSR,OLSR,and AODV commonly used in MANET at present.The simulation results show that compared to traditional OLSR,SA-OLSR can reduce nearly 10% of HELLO packet control overhead ininterference networks and reduce the probability of long-term congestion in the network; compared with AODV,SA-OLSR has a loweraverage latency and relatively stable latency fluctuations. At the same time,it can greatly increase the throughput of the network.
