【摘要】 利用多个信道接口来改善adhoc网络信道容量。即一个信道周期性的广播节点状态信息分组来维护全网所有节点的状态信息,而另一个信道利用此信息采用最短路径搜寻算法来获得到目的节点的路由并完成数据传输。这样充分结合了表驱动路由方法和按需式路由方法的优点。另外,信息维护与数据分组分别在两个信道内同时进行,避免了信息维护对数据分组传输的影响,提高了网络性能。更多还原

【Abstract】 By improving the capacity of ad hoc networks by using multiple channel interfaces,a dual channel routing(DCR)scheme was introduced that proactively maintains all nodes’ location information based on periodic exchanges of location information in one channel.Based on the information,shortest path algorithm was used to find route to destination.Then,source transmitted data packet in another channel.DCR is a hybrid proactive/reactive scheme.Because there is no interference between two channels,the results of simulation show that the scheme can improve networks performance.更多还原
