SDWSN: Software-defined wireless sensor network

Abstract

Nowadays, several protocols and treaties coexist in the Internet world that dispenses the services to the users. But the distributed management and the control decisions make the network modest to control. Due to these problems, the behavior of the network becomes unpredictable and insufficient. Hence, there is a lack of flexibility in the conventional network architecture like in Wireless Sensor Network (WSN). Therefore, Software-Defined Networking (SDN) finds the deficiencies of the previous technologies and isolated both the planes named as control and data plane. It aims to make the network more simplified and flexible with respect to that of the traditional one. The SDN application in WSN is very commanding in terms of network configuration and network management, leading to an emerging network technology known as Software-Defined Wireless Sensor Network (SDWSN). Therefore, the paper presents the challenges in SDWSN in terms of the management and configuration of the network. The pitch is to comprehend the current challenges with an end goal to ensure more security, efficiency, and dependability. We reviewed several works of literature such as SDN, WSN, and SDWSN and present the findings in terms of architecture, challenges, and their solution. This paper shows how SDN is included in WSN to solve the existing challenges.
