Energy and QoS Efficient Load Aware Routing Protocol for Mobile Ad Hoc Networks

Efficient load balancing in Mobile Ad Hoc Networks (MANETs) is widely studied research problem since from last decade. The performance of MANETs routing protocol becoming weak because of frequent routes failure and other constraints such as less capacity, high traffic, less energy etc. In short, load balancing is major cause of frequent routes failure in MANETs. Frequent routes failures always resulted in overall QoS performance degradation in MANET. There are various load balancing techniques introduced by considering the different constraints and characteristics of MANETs routing. The goal of any routing protocol should be optimal performance from routing communications. The existing routing efficient protocols does not guarantee for all the performance metrics efficiency such as energy efficiency, QoS efficiency, routing overhead etc. Some load balancing enabled routing protocols providing the QoS efficiency but failed to achieve the energy efficiency and vice-versa. By considering all the limitations of existing load balancing enabled routing protocols, in this paper novel EELAR routing protocol is designed. The goal of EELAR routing protocol is to achieve the optimized performance for QoS and energy efficiency as compared to all previous routing protocols. EELAR is designed by contributing two algorithms such as link efficiency algorithm and load efficiency algorithm.
