Cooperative Diversity with Disconnection Constraints and Sleep Discipline for Power Control in Wireless Sensor Networks
2006 (English)In: 2006 IEEE 63RD VEHICULAR TECHNOLOGY CONFERENCE, IEEE , 2006, 578-582 p.Conference paper (Refereed)
We derive a power control policy for a group of sensor nodes that are monitoring a real-time application sensitive to disconnections (outages) of the communication. Specifically, we suggest that the sensor nodes perform cooperative diversity while running a sleep discipline. After the description of a detailed model of the wireless links, we propose a power minimization algorithm with a constraint expressed in terms of outage probability. Suboptimal solutions are also discussed. Numerical examples are provided for various number of nodes; wireless scenarios and nodes activities. It is argued that nodes with reduced activity show better performance.
