　　研究方向
　　Research Topic：sink mobility problem in WSN
　　We proved that the problem of scheduling multiple mobile sinks among limited locations with the objective to maximize network lifetime belongs to class NP-complete and developed an exponential-time enumeration based algorithm，which guarantees an optimal solution and serves as an upper bound．
　　Research Topic：target coverage problem in WSN
　　We developed a lifetime upper bound via a linear programming （LP） formulation by relaxing coverage constraints for this problem．Then we utilized a column generation （CG） based approach to find a feasible schedule to approach this upper bound．Numerical results demonstrate that our CG based approach constantly yields optimal or near-optimal solutions and thus provides a critical performance benchmark when evaluating other heuristic algorithms．
　　Research Topic：target tracking problem in WSN
　　We built a prediction model to predict the Potential Future Area （PFA） a target may present based on previously collected information，like moving direction，moving speed，etc．The key idea is clear：to save energy by turning on only sensor nodes in PFA．This scheme outperforms other similar mechanism in terms of total energy consumption and communication bandwidth requirement，proved by not only theoretical analysis but also simulation results．
