EECMRP: ENERGY EFFICIENT CLUSTER MULTIPATH ROUTING PROTOCOLFOR MANETs

Abstract

The overall performance of the computer network depends on the Quality of service (QoS) parameters such as delay, jitter, variance, bandwidth, throughput, packet delivery ratio etc. In order to further enchance the quality of communication over mobile ad hoc networks (MANETs), this paper proposes an Energy Efficient Clustered Multipath Routing Protocol (EECMRP).Delay being the most important parameter in the transmission of multimedia datacan be minimizedby considering the concept of multipath along with clustering The multipath concept aims at finding more than one path for the transmission of data from the source to the destination. There are two criteria involved one is the stability of the link and the reliability of the link which determines the quality of the link.This provides an efficient measure for cluster retransmission in an energy efficient manner and also reduces delay.Cross layer communication between physical, MAC and routing layers has helped to achieve QoS in the network by establishing more stable and reliable paths, thus reducing the delay.Performance evaluation of the proposed protocol against AODV and QMRP has been conducted using network simulator. Results show that EECMRP outpaces QMRPand AODV in terms of energy efficiency and delay.Routing overhead for QMRP is more than that in AODV as it establishes multipath concept. Further, routing overhead of EECMRP is reduced when compared with QMRP due to the use of clustering concept in each route detection process.
