An Adaptive Load Balanced on Demand Routing Protocol

Mobile ad hoc networks are a type of mobile network that functions without any fixed infrastructure. Routing protocols are vital for the proper functioning of ad hoc networks. In the present routing protocols, data is transmitted after choosing shortest path without any consideration of any particular node´s traffic which raises the problem of delay of transmission and unbalanced energy consumption. In this paper ,a new routing metric is introduced to the protocol which selects the lightest loaded path with the largest residual energy for data routing all of the time, thus improve the packet delivery rate and lower the average delay. A comprehensive simulation study was conducted to evaluate the performance of the proposed scheme. Performance results also show that the proposed protocol outperforms existing ad hoc routing protocols in terms of packet delivery and average end-to-end delay.
