In wireless sensor networks, many sensors face energy constraints and can switch among different work modes to save energy. How to properly schedule work modes is important for network utility maximization (NUM) in the long run. This paper proposes multiperiod scheduling to maximize total network utility by considering energy constraints and periodic sensing requirements. This NUM problem presents...
Traditional macro-cell networks are experiencing an explosion of data traffic, and small-cell can efficiently solve this problem by efficiently offloading the traffic from macro-cells. Given massive small-cells deployed in each over-crowed macro-cell, their aggregate power consumption (though low for an individual) can be larger than that of a macro-cell. To reduce the total power consumption of a...
