Joint Optimization of System Lifetime and Network Performance for Real-Time Wireless Sensor Networks
15 years 11 months ago
Maximizing the aggregate network utility and minimizing the network energy consumption are important but conflict goals in wireless sensor networks. Challenges arise due to the app...
