Adaptive Multi-Path Parallel Forwarding Mechanism in Mobile Ad Hoc Networks

The probability of successful packet delivery in ad hoc networks can be guaranteed by multi-path routing scheme, which can enhance network reliability. With the analysis on the path number, a decision making method based on packet drop ratio is introduced; moreover, a novel adaptive multi-path routing protocol is proposed. By monitoring packet drop ratio on the links, mobile nodes estimate link status with the pre-defined threshold, thus the partial-disjoint multi-path can be established under current network topology adaptively. Simulation results show this mechanism can provide reliable transmission for data packet and enhance the performance of the entire network while utilizing the network resource effectively.
