In Wireless Sensor Networks(WSNs),the unstable links and nodes fail ure are high likely to occur due to the energy depletion,hardware malfunction and malicious invasion,which might give rise to the dynamic changes of net work topology and decrease the coverage of the network.Due to this reason,the performance of the entire network would also be negatively influenced.Software Defined Network(SDN)is characterized as centralized controlling,relaying and controlling in separate way,virtualizing and visual programming,which is able to provide flexible,automatic application framework.Thus,aiming to improve the invulnerability of WSNs,we propose an invulnerability framework of WSN,illustrated by Figure 1,based on SDN.
