英文摘要： Combining software defined network technology with wireless sensor network, the definition and architecture of software defined sensor network (SDSN) are proposed. The network reconfiguration technologies of SDSN including coverage optimization, topology control and routing optimization are researched in detail, in order to acquire the innovation achievements on the key technologies and related theories. The contents and objectives for this research are as follows. Firstly, the theory of Voronoi graph is used to search the optimal allocation of sensing radius to ensure the energy balance in full coverage, and also to find the optimal subset of sensor nodes and their sensing radius to achieve K-coverage on target region. Secondly, based on the theory of simplicial complex, the efficient calculating algorithm of edge chain group minimal generator is studied in the pre-power allocation, and the efficient iterative algorithm is also studied in the power reconfiguration. Finally, the optimal algorithm for routing is studied to guarantee the QoS requirement of each serve in the multi-serve transmission and to balance the residual energy of each sensor node in the whole SDSN. Through in-depth theoretical analysis, carefully designed computer simulation and necessary assistant experiments, the proposed algorithms will be verified. The proposal aims to systematically complete the above tasks, making valuable contributions to practical wireless communication systems.
