IOR-WSN: Intelligent and Optimized routing protocol to enhance the network lifetime of wireless sensor networks

Abstract

With the advent of the Internet of things, recent years of research is more focused onthedevelopment of energy-efficient routing protocols that play a vital role in the context of communication among various sensors that are deployed in geographical locations. Addressing this problem, several studies have contributed in the development of energy-efficient protocols; one among them is LEACH (low-energy adaptive clustering hierarchy). It is considered as an application-specific protocol in the context of wireless sensor networks (WSN’s). Despite the consideration of the cluster heads (CHs) in the rotation basis, the LEACH protocol will increase the energy consumption of the network.Even though several versions of heuristic energy-efficient algorithms are developed by enhancing the capabilities of the LEACH protocol, it is observed that still there exists considerable pitfall in the hierarchical routing protocols. The main objective of this paper is to develop an optimized network topology that enables the sensors to communicate based on acknowledgment-based node distance estimation and optimized network mapping using signal strength. The simulation results depicted in the paper illustrates the performance threshold for the proposed mechanism exceeds in the sense of numerous parameters when contrasted with traditional routing protocols, which involve initial node energy, residual node energy, and total network energy.
