ABSTRACT
The software defined networking (SDN) concept promises to make network setup and resource management much easier. Because such capabilities are useful to network operators, the industry (as well as academic) research and development community is increasingly focused on SDN. Wireless sensor networks (WSNs) are a contemporary networking and computing platform that use wireless sensors to share information. Powerful network capabilities are in great demand in today's network computing applications. Functional network reach is critical to client satisfaction in mobile networks and cloud computing environments. However, network management and control are much more difficult in WSNs. Wireless equipment manufacturers are beginning to adopt to adopt SDN-related control for sensors. This chapter explores the SDN control and management activities regarding WSNs. We investigate whether the SDN method used in WSNs provides flexibility, enhances management, and improves overall performance. We emphasize how network policies can be implemented in WSN under the SDN umbrella. Different types of network policies are also discussed regarding SDN-based WSNs.
