摘要：Since sensor nodes have limited battery power, it is desirable to select a minimum set of working sensor nodes which should be involved in sensing and forwarding data to the sink. In this paper, we propose a disjoint scheduling for density control in wireless sensor network to achieve the desired robust coverage as well as satisfactory connectivity to the sink with a small set of working nodes. Simulations showed that our scheme works well in an energy efficient fashion by turning off too many redundant nodes.
