Abstract：The probability of packet delivered in Ad hoc network can be guaranteed by the multi-path scheme, with the analysis on the path numbers, the decision method based on packet drop rate is introduced; furthermore, the segment adaptive multi-path routing protocol is proposed. The mobile node estimates its status with the threshold pre-defined by monitoring the packet drop rate on the link, so the segmented multi-path can be established under current network topology, then the relay nodes can be selected adaptively. Simulations results show that the protocol can provide the reliable transmission for data packet while utilizing the network resource effectively.
