Codes for Sensors: An Algorithmic Perspective,over a network of independent channels. Based on this formulation, we are able to characterize the network capacity, i.e., the exact conditions on the sources and the channels under which there exist codes for reliable communication with the data collection point. An important conclusion to be drawn

Efficient Sensor Network Design for Continuous Monitoring of Moving Objects,xpected time achieves a .(log. ) approximation ratio to the optimal solution. Our network design solution can be combined with alternative collaborative processing methods, to suitably fit different tracking scenaria.

Correlation, Coding, and Cooperation in Wireless Sensor Networks,ate with each other and employ . at the base-station. The chief contribution of the paper is to show that the computational complexity of our problem is determined by the complex interplay of various system-level opportunities and challenges.

Assigning Sensors to Missions with Demands,t to .-. (with .?=?.), which yields a polynomial-time (.+1)/2-approximation. For .=?2, we solve the problem optimally by reduction to maximum matching. Finally, we introduce a geometric version which remains strongly .-hard but has a PTAS.
