چکیده
Routing real-time traffic with good Quality of Service (QoS) is a challenging task in Mobile Ad-Hoc Networks (MANETs). Energy Aware Fuzzy based Multi Constrained Single path QoS Routing (E-FMSQR) protocol which is an extension of AODV is proposed to find an optimal path by considering multiple QoS metrics. Considering Multiconstraints like Bandwidth, Delay, Number of Hops and Energy, a single fuzzy cost is determined as output cost. The protocol also computes Link Expiration Time (LET) based on the speed and direction of movement of the mobile node to predict the nodes mobility to identify a stable path. An optimal path is chosen as one with minimum output cost and maximum LET. Path breakage due to link failure or node failure is prevented. The simulation result shows the improvement in throughput and packet delivery ratio with minimum delay. It shows better energy distribution among nodes minimizing node failures in the network and maximizing the network Lifetime.
