So that its routing problem an important research subject accordingly. In all the proposed protocols, the Ad Hoc On-demand Distance Vector Routing Protocol(AODV) is applied to most wireless environments. With it, the shortest path from the source to destination node is chosen by the metric of hop counts. However, the chosen path with this metric may not be a stable one. With the research of predecessors, the Link Available Time(LAT ) can be calculated by the strength of received signal and may be regarded as another usable routing metric. Based on that, the authors develop a protocol named AODV-Deleting Path with Bad Broken Index (AODV-DPWBB) and discuss all the logicality of it. The simulation is done for two contention modes in several node speeds with discussion followed. The simulation result shows better throughput, and end-to-end delay can be obtained comparing the original AODV with metric of hop-count. 展开更多
