The mobile adhoc networks are the infrastructureless networks constructed without any fixed infrastructure such as base station, tower, redirection switches and routers. Mobile adhoc networks are the temporary wireless networks. All the routing information are managed by the node itself. Mobile adhoc network routing operations are categorized into two types proactive and reactive routing. The multipath routing mechanisms are used to discover multiple paths under the nodes.
Multipath dynamic source routing protocol (MPDSR) is used to discover multipath route under MANET nodes. The MPDSR protocol uses the local link information for the route discovery process. The MPDSR protocol is enhanced with ant colony optimization method to provide multipath route information using global link information. EMPDSR provides QoS factors such as endtoend reliability. Network traffic, bandwidth and battery power factors make an influence over the route discovery process.
Cost enabled route discovery is one of the consierable routing method that enables the cost estimation with different metrics. The multipath routing protocols concentrates on the route discovery with end to end reliability factors. The EMPDSR protocol is integrated with fuzzy cost estimiation techniques. Distance, network traffic, bandwidth and battery power metrics are used in the fuzzy cost enabled multipath dynamic source routing protocol.
