An Intelligent Opportunistic Routing Protocol for Big Data in WSNs

Opportunistic routing (OR) is an emerging and promising data communication protocol in wireless sensor networks (WSNs). The OR becomes more important when the routing of data is Big Data (BD) generated from multidimensional distributed sensors nodes. The central idea behind OR is overhearing and coordination between relay nodes in the forwarders list and management of multidimensional BD. It uses the salient broadcast feature of the wireless medium for achieving advanced reliability and maximizing the communication range. This article presents the basic concepts of WSN, reviews different OR protocols, and describes the use of different machine learning (ML) techniques in routing BD. Current issues and challenges associated with WSN in general and OR in particular are also presented in this article.
