Title
Dynamic Sensing Scheduling To Prolong Network Lifetime Under Practical Requirements
Abstract
We propose a unique Dynamic Sensing Scheduling (DSS) scheme to prolong the lifetime of a sensor network. Different from most existing works, we study the sensor network lifetime under two practical requirements: sensing coverage and network connectivity. A sensor node is considered critical if its depletion of energy would cause either a violation of the sensing coverage requirement (specified by the application) or a disconnection of the routing tree. The key idea of DSS is to adjust the sensing duties of sensor nodes according to their nodal lifetime as well as their criticality. Under this design principle, DSS schedules more sensing duties to non-critical nodes (even at the cost of losing them more quickly) so that critical nodes may stay alive for a longer period of time, thus extending the network lifetime. DSS adjusts the sensing duties between neighboring nodes only, and is a distributed and lightweight solution. Simulation results show that DSS performs well under various network setups, close to a theoretical upper bound.
