摘要：
We focus on the topology control algorithm in Software-Defined Sensor Networks (SDSNs) and propose a robot-assisted sink nodes relocation algorithm based on the Markov chain. Firstly, by using the software-defined architecture, sensor nodes and network topology can be deployed and updated by the controller which provides global network information and centralized management in real time. Then robot-assisted sink nodes are deployed into SDSN to extend the network lifetime. Unlike motionless nodes or random mobile nodes which may bring about unforeseeable network topological variation, robot-ass...
