Exploitation of OpenFlow in wireless sensor networks

A novel idea presented in this paper is to exploit the OpenFlow technology to address reliability, which is one of the most important factors in sensor networks. The proposed approach unified with flow-sensor and communication with controller. Hardware to programmable hardware, operating system to network operating system, vendor to owner specific, previous hardware defined networking (device monitoring, traffic controlling, and topology definition) turns to be software defined and where everything leads to a programmable and customized networking system. OpenFlow bears the characteristics to control the flow-sensor and monitor sensor traffic flow that also addresses another two important problems robust routing and load balancing. Flow-sensor displayed much better performances in comparison to typical sensors through generating less number of packets with lower simulation time in ideal scenario and even better results are possible for larger networks.
