Reliable and energy-aware routing in mobile ad-hoc networks

In a Mobile Ad-hoc Network (MANET), energy-awareness is a crucial design issue as it consists of a group of mobile nodes. The mobile nodes with limited battery power act as router in MANET. Though establishment of an appropriate and efficient route is an important design aspect, a more challenging task is to establish and select a reliable and energy-efficient route between a source-destination pair. Thus, power failure of mobile nodes constituent a route influences data routing, link failure and network lifetime. Therefore, to meet the above mentioned goal and overcome energy-aware routing design issues, in this paper routing protocols are proposed to construct reliable and energy-aware routes considering energy consumption and remaining energy of nodes. The remaining energy and energy_factor (the ratio of remaining energy and initial energy of a node) are used as important parameters for selection of a node in a route. Under considered parameters, the proposed routing protocols ensure reliability and energy-awareness in MANET and avoid link failure due to node's low power in an established route. Simulation results show that the proposed routing protocols perform better compared to the similar kind of popular existing routing schemes in terms of energy consumption, throughput, delay and routing overhead in different network scenarios.
