ERA-AODV for MANETs to improve reliability in energy-efficient way

Abstract

The nodes in MANETs communicate with each other through wireless medium and are constantly moving. To maintain the links in a continuously changing topology is a challenge, especially for longer duration of time, and in such scenarios, the reliability of the links becomes the prime issue. Further, the reliability must be maintained in an energy-efficient way. The paper presents energy-efficient version of RA-AODV named as ERA-AODV which measures reliability in terms of end-to-end delay, bandwidth, and mobility of the intermediate nodes. Since the prime factor which determines the consumption of energy of the node is the distance of communication between them, the proposed scheme takes into account adjustment of the transmission range of the mobile nodes according to residual energy, to provide improved energy efficiency. The parameters considered as performance measure which include packet delivery ratio, throughput and remaining energy demonstration improvement over the existing scheme.
