An Adaptive Protocol for Stable and Energy-Aware Routing in MANETs
Sajal Sarkar, Raja Datta · IETE Technical Review · 2016
In mobile ad-hoc networks (MANETs), routing protocols are impaired by its nodes’ mobility, misbehaviour, and insufficient battery power. In order to overcome the above-mentioned impairments of routing protocols, in this paper, we propose a multiple routing metrics based stable and energy-aware routing protocol. In route discovery phase, our proposed protocol establishes a stable, secure, and energy-aware route from a source node to a destination node based on the multiple routing metrics derived considering mobility, energy level, and data packet forwarding statistic of mobile nodes. In route maintenance phase, the protocol monitors neighbours of the intermediate nodes so that it may minimally redefine the established route whenever a link gets disrupted or a node reaches a threshold value with regard to its routing metrics. A trust module is also included in the proposed protocol which gives inputs regarding nodes’ trustworthiness so as to keep a path as reliable as possible. Simulation results show that our protocol increases packet delivery ratio and reduces average end-to-end delay and average energy consumption in different MANET scenarios.
