Energy efficient link stable routing in internet of things

In future communication networks with Internet of Things (IoT), each of the smart devices will be able to communicate with other smart devices ubiquitously throughout the time clock. These smart devices contain limited amount of energy, memory, and processing power. Additionally, short range radios are very susceptible to noise, multi route distortion, and interference. In this context this paper proposes an energy efficient link stable routing (EELSR) to conserve energy of the smart devices and to account link stability for enhancing the network lifetime. In order to verify the correctness of the proposed routing, first, analytical models for link stability, and residual energy of a route have proposed, second, an optimal route selection algorithm that uses residual energy of a route, link stability of a route, and route distance, has been designed. The performance of the proposed EELSR is evaluated and compared with AODV and REL in the terms of network life time, packet delivery ratio, routing success probability, and route setup delay. EELSR outperforms the state of art routing algorithms.
