Performance Analysis of Different QoS Routing Protocols to Minimize Power in Heterogeneous Network

Power consumption of nodes in ad hoc networks and fixed network is major issue in current world. The lifetime of network will be improved by suitably reducing the requirement of power for connections. There is a challenge to provide QoS solutions that operate seamlessly over wired-wireless domains and maintain end-to-end QoS with user mobility. In this paper we have proposed different QoS Multipath routing protocols for heterogeneous network. Multipath routing separates the traffic among different paths to minimize congestion in terms of multiple alternative paths through a network which can provide a variety of benefits such as minimize delay and congestion , maximize bandwidth or improved security. Different types of adhoc routing protocols are discussed in this paper such as Ad- Hoc On-Demand Distance Vector (AODV) , Ad-Hoc On Demand Multipath Distance Vector (AOMDV). AOMDV is the extension of AODV routing protocol. These routing protocol are used in wireless network which is designed to form multiple routes from source to the destination and also avoid the loop formation so that it reduces congestion in the channel. The NS2 simulation result shows that the performance analysis of AODV and AOMDV protocols in hybrid environment and comparison done based on power consumption, average end to end delay, bandwidth , routing overhead and packet delivery ratio by varying the traffic load in the network.
