QoS aware Hierarchical Multi-hop Routing Protocols in MANETs

Ad hoc wireless networks are multi-hop networksthat are dynamic, and are formedby a group of nodeswhich are mobile in nature,on a shared wireless links.Mobile ad hoc network (MANET) is a collection ofautonomous nodes that communicate with each other by forming a multi hop radio network.The analysisand design of routing protocolsis a significant issue in ad-hoc wireless networks.Sincethe previouslyproposed routing algorithmshave not considered the multi-hop flow with an end-to-end scenario, andhadshown to perform well in providing blond sharing of bandwidths among the single-hop wireless flow.Compared to host-based routing,Hierarchical Multi-hop routingsignificantlyreduces the routing tablesizesand the amount of routing related signalling traffic, at the expense of reducing path efficiency andgenerating some management traffic
