Abstract--We propose "mode switch", an adaptive loadsensitive solution that supports both an energy-efficient operation mode for transmitting normal sensor data and an Qo...
Abstract. In the micro-cell-based PCS networks, due to the high user mobility, handoffs occur more frequently. Hence, the classical assumptions, such as the exponential assumptions...
