Abstract

Wireless Sensor Networks (WSNs) are commonly used information technologies of modern networking and computing platforms.Wireless Sensor Networks (WSN) consist of low power devices that are distributed in geographically isolated areas. Sensors are arranged in clusters. Each cluster defines a vital node which is known as a cluster head (CH). Each CH collects the sensed data from its sensor nodes to be transmitted to a base station (BS). Sensors have deployed with batteries that cannot be replaced. The energy consumption is an important concern for WSN. Today’s network computing applications are faced with a high demand of powerful network functionalities. Functional network reach is cen- tral to customer satisfaction such as in mobile networks and cloud computing environ- ments. However, efficient management of WSNs remains a challenge, due to problems sup- plemental to them. Recent technology shift proposes Software Defined Networking (SDN) for improving computing networks. This review paper highlights application challenges faced by WSNs for monitored environments and those faced by the proposed approaches, as well as opportunities that can be realized on applications of WSNs using SDN. We also highlight Implementation considerations by focusing on critical aspects that should not be disregarded when attempting to improve network functionalities. We then propose a strat- egy for Software Defined Wireless Sensor Network (SDWSN) as an effort f or application improvement in monitored environments.
