We aim to save energy by scheduling periodic sensors' duty cycles. Different from existing works, we integrate two important tasks, collision avoidance and duty cycling, into one scheduling of sensors' activities. Our scheme consists of two parts: a coloring scheme that assigns a "color" to each sensor and a color scheduling scheme that associates each color with a schedule. Each sensor...
In this paper, we put forward a power-aware static scheduling algorithm for sensor network - PAS. It is the first static scheduling algorithm designed for sensor network. The test result compared with another two algorithms HLFET and MCP is presented. It shows that our algorithm give better performance on extending the lifetime of the whole sensor network.
