Enhanced clustering ant colony routing algorithm based on swarm intelligence in wireless sensor network

Abstract

Major issues in wireless sensor networks are performance enhancement and optimize QoS parameters. Paper proposes a novel QoS Algorithm for optimum path routing with routing matrices. Most renowned Dijkstra's algorithm focuses on shortest path but less efficient in congested network. Afterwards, improved ant colony routing algorithm IPACR enhance coverage rate by finding optimum alternate path routing. Cluster-based ant colony routing algorithm ICACR introduced as simplified version and outperform IPACR by lifetime of network, but not efficient when Sink node is close to Source node. Enhanced cluster based algorithm ECACR is proposed in this paper, as enhancement in ICACR in terms of fast PD ratio through sensor nodes and less congested shortest path in wireless networks.
