Disjoint multi-path QoS routing in ad hoc networks

In this paper, we investigate a disjoint multi-path QoS routing in ad hoc networks, which reactively collects link-state information from source to destination. We propose a route discovery algorithm to find multiple disjoint paths, which can offer most aggregate resources to meet the QoS requirement of a call. We also propose a method for choosing proper paths, namely LBHBF. The simulation results show that disjoint multi-path QoS routing scheme increases the success rate and decreases the cost of network resources in various network environments.
