Wireless Sensor Network Performance Enhancement using Software Defined Networking Principle
Journal of System and Management Sciences · 2022
A great effort has been dedicated by the networks research community to study Wireless Sensor Network (WSN) to overcome its challenges and optimize its performance.Software-Defined Networking (SDN) has been paid attention thanks to its innovative features, which has been deployed to multiple types of networks instead of traditional network architectures.Recently, the researchers are trying to apply SDN technology on WSN to utilize its advantages such as ease of management, being reconfigurable and ease to revolve using various product vendors.Besides the benefit of delegation, a lot of tasks to the base station (controller) which has unlimited power instead of the sensors and that will affect positively the power consumption and the sensors' lifetime.Low-Energy Adaptive Clustering Hierarchy (LEACH) is a routing protocol for hierarchical networks that prolongs the lifetime of sensors.Its proficiency in reducing power consumption has been proved in a lot of WSN projects.In this paper, the LEACH protocol i s integrated with SDN technology on WSN so that it could save sensors' power, reduce overhead and give longer time to the network aside from taking benefits of SDN.The proposed strategy met its objectives, as evidenced by studies that indicate a 33% reduction in energy usage and a 56% increase in sensed data over flat SDN networks.It also provides a significant reduction in energy consumption when compared to the LEACH technique.
