摘要
In this paper, we explore the operations of probing environment sensor networks and force to define some mathematical models to describe the operations. By these models, a probing radius adjusting mechanism "PRAM" has been provided to control the trade-off between energy efficiency, network scalability and sensing rate. PRAM can estimate the desirable probing range to minimize the energy consumption based on the premise that the required sensing rate and scalability of WSNs can be satisfied. Simulation results show PRAM can adjust exactly the value of probing range to satisfy the required sensing rate and extend substantially the life time of sensor networks.
