摘要：In Mobile ad hoc networks (MANET), the quality of service (QoS) depends on the available resources in the network and node mobility as mobility may result in frequent route failures. Some existing hybrid approach of multi-path routing technique rarely considers QoS metrics for path selection. In this paper, we propose a QoS enhanced hybrid multi-path routing protocol for MANET. In this protocol, topology discovery is performed proactively and route discovery is performed in the reactive manner. In proactive topology discovery phase, each node collects the battery power, queue length and residual bandwidth of every other nodes and stores in the topology information table (TIT). By exchanging the TIT among the nodes, the topology is discovered. When the source node wants to forward the data packet to the destination, it utilizes the reactive route discovery technique where the multiple paths are established using multi-path Dijkstra algorithm. When any intermediate node does not recognize the next 2-hop information from TIT towards destination, the new multi-path route discovery is performed. By simulation results, it is shown that the proposed approach reduces the overhead.
