| 摘 要： | 对于Ad Hoc网络多路径机制来说,采用过多的路径传输数据会影响网络的资源利用率,同时固定的选取路径数量也不能够使得多路径机制适应各种拓扑情况。提出了自适应部分多路由机制,首先分析分组丢弃概率门限问题,节点使用该门限值判定链路状态,并且根据网络当前的拓扑状态自适应地寻找部分多路径。仿真结果表明,该机制在减少路由建立开销的同时,能够有效保障数据分组传输的可靠性。

| Abstract: | For the multi-path schemes in ad hoe network,the efficiency decreases with the excessive number of path,and the schemes can not adapt the topology with the fixed number of path.The adaptive partial multi-path scheme was proposed. The analysis of choosing threshold for packet drop rate was introduced;the mobile node estimates the links status with this threshold and finds the adaptive partial multi-path under current network topology.Simulations results show that with the reduction of control overhead for pa... |
