A Neighbor-information-based Node-Scheduling Scheme in Wireless Sensor Networks
In wireless sensor networks that consist of a large number of Iow-power, short-lived, unreliable sensors,one of the main design challenges is to obtain long system lifetime, as well as maintain sufficient sensing coverage and energy reliability. In this paper, we propose a node-scheduling scheme which can reduce system overall energy consumption,therefore increasing system lifetime, by turning off some redundant nodes. Some nodes can be put into the sleep state while other sensor nodes remain active for the sensing and communication tasks. In our scheme each node decides its state by using its own and its neighbors- location information.And we compare the scheme to ACK scheme.
