Study on coupling of software-defined networking and wireless sensor networks
Younghwan Choi, Yun-Chul Choi, Yong-Geun Hong · 2016
Typically, wireless sensor networks (WSNs) provide application-specific networking schemes based on restricted resources. For the reasons, WSN-based routing algorithms can be variously designed for applications. Even if two different WSN applications (e.g., target tracking and temperature monitoring) coexist in a network, the two applications can use different routing algorithms, running simultaneously on the same sensor nodes and network. However, the sensor nodes can efficiently spend their restrict resources (e.g., battery power) unless the two algorithms need to run simultaneously. There are a few research tries to deal with this problems by combining sensor networks with basic concepts of software-defined networking (SDN). However, performance of such a combination needs to be fully evaluated because the basic concept of SDN could not always give a positive effects to WSNs. Thus, this paper gives a try to analyze coupling of SDN and WSNs.
