Adhoc on Demand Multipath Reliable and Energy Aware Quality of Service Routing for Mobile Adhoc Networks

Abstract: Problem statement: In a mobile adhoc network, there are a number of challenges for providing quality of service routing for multimedia applications and real time applications like voice transmission. The QoS parameters considered in this study are link reliability and energy consumption. Existing studies estimate the link reliability constraint between two nodes using exponentially distributed epoch lengths. The major problem in this approach is that the nodes are having memoryless property and the hazard rate is independent of time. Approach: In study, an analytical expression is proposed to estimate the link reliability of MANET when the nodes have identical weibull distribution where the hazard rate is a function of the time. Adhoc On Demand Multipath Reliable and Energy Aware QoS Routing (AOMP-REQR) protocol is designed by including the QoS constraints (Link Reliability and Energy Consumption) in the existing protocol AOMDV, which finds the multiple link disjoint stable paths. Results: Simulation results show that the proposed algorithm achieves better packet delivery ratio with reduced energy consumption and delay. Conclusion: Since the proposed analytical method estimates the link reliability in better way, AOMP-REQR protocol finds the multiple link disjoint stable paths and also the energy consumption is less
