ABSTRACT
Mobile communication plays an important role in disaster recovery management during emergency situations. It is helpful in situations where the system has less robust and less flexible fixed infrastructure. The Disaster recovery management systems require timely interaction and coordination in order to save lives and property. Energy consumption in heterogeneous network is a major issue , whether they operate within a base station infrastructure , fixed network or in a free-standing Mobile Ad Hoc Network (MANET). The lifetime of network will be improved by suitably reducing the requirement of power for connections. There is a challenge to provide Quality of Service (QoS) solutions to wired cum wireless domains and maintain end-to-end QoS in ad hoc network. In this paper we propose a new protocol Power Aware QoS Multipath Routing protocol (PAQMR) for disaster recovery network. This protocol is the enhanced protocol of Ad-Hoc On Demand Multipath Distance Vector protocol (AOMDV). This routing protocol is used to avoid the loop formation in network so that it reduces congestion in the channel. The Network Simulator (NS-2.34) tool is utilized to measure the performance of AODV, AOMDV and PAQMR protocols in hybrid environment. The metrics for the simulation are energy consumption, average end to end delay and packet delivery ratio by varying the traffic load and pause time in the network. The results shows that the proposed protocol minimize the power, delay, congestion and maximize the packet delivery ratio.
