KMHSO: k-Means and Harmony Search-Based Optimization Algorithm for Relay Node Selection in Smart Transportation System

Abstract

With the arrival of the internet of things and advancement in every front of technology, the field of the smart transportation system is becoming prevailing among the researchers. To avoid the problems in existing transportation systems and to provide better services and information to its users, smart transportation system can be used. This paper incorporates the wireless sensor network (WSN) technology with the smart transportation system. WSNs play a vital role in monitoring and gathering information from the environment. To provide better coverage and connectivity with least message overhead, this paper uses a combination of k-means and harmony search algorithm. The proposed approach is compared on the basis of parameters like message overhead, coverage, throughput and end-to-end delay. The simulation results show that the proposed work is efficient, provides good coverage and reduces message overhead.
