Research Of Energy Efficiency On Software Define Wireless Sensor Networks

Software defined wireless Network SENSOR Network,as a new proposed concept,we add the SDN into traditional WSNs,Which helps us to solve the limitation in WSNs.Wireless Sensor Networks,as a typical frame work of Wireless Network,has gained tremendous attentions,the main reasons are easy to deploy,low cost,dynamic adaption.As mentioned,WSNs are brand applied,such as medical treatment,architecture as well as military.As the development of 5G and IOT,IOV,Smart Home,Smart City,the standard of WSNs has been risen,so the traditional network architecture can not satisfied the need of wide band,big data,multi-scenario as well as multi-protocol,which brings attention to the SDWSNs.SDWSNs work in the concept of central controlling and separating of data and control.The center controller takes charge of calculation the routing table,and control the network to balancing the consumption.Our thesis is proposed upon the concept we mentioned.We bring the Software Define Networks to the traditional Wireless Sensor Network to separate the data and controlling as well as center control.The controller can calculate the best routing table after it gets the topology of entire network and then delivers the routing table to sensor nodes.Our research is based on the background we raise,and we learn a lot from the key technology of SDN.Our work includes as follows:1.We analyzed the key technology of traditional WSNs,and we make some sense of its disadvantages.As well,we combine WSNs and SDNs and make progress.2 We use wireless signal to control the open or shot down of the sensors.3 We propose an algorithm about clustering and energy shell related,which can make energy consumption more efficiency.And we simulate it.
