| 摘 要： | OLSR路由协议中，MPR节点的选择以连接度为参考标准．实际上，随着节点的增加和移动速度的加快，由于某些MPR节点的空闲度降低而造成节点拥塞加剧，降低了网络的性能．以节点空闲度和连接度均衡考虑对MPR选择算法做出改进研究．实验结果表明，改进后的OLSR路由协议在数据传输成功率与时延等方面都有显著提高．

| Abstract: | The selection of multi- point relays （MPR） nodes depends on the degree of connection in the optimized link state routing protocol （OISR）. In fact, with the node number increasing and the moving speed intensifying, the algorithm can add the overhead of routing because of free-degree, and the network performance is reduced. This paper improves MPR selection algorithm based on a balanced consideration of free-degree and connectivity. The experimental result indicates that the improved OLSR routing protocol has significantly improved the transmission success rate of data, time delay and so on. |
