Data applications may typically tolerate a moderate delay before packet\ntransmission between user equipment (UE) and cell begins. This delay can be\ntaken advantage to reduce the communication distance, improve coverage\nprobability, and increase overall energy-efficiency of the small cell network.\nTo demonstrate such merits, we suggest a simple access scheme and analyze the\ndistribution of coverage probability and throughput as a function of delay and\ntransmit distance. Sufficient number of small base stations (SBSs) handle the\npeak traffic load. To improve energy-efficiency of the network, a number of\nSBSs are switched off at low traffic periods. Energy-efficiency can be further\nimproved by turning all of the SBSs on and off, rather than selecting a subset\nand leaving them off. By doing so, coverage probability and bit-rate can be\nimproved by delaying their transmissions and waiting for a closer SBS to become\navailable. Results show that by turning SBSs on and off continuously and taking\nadvantage of initial delay to connect a SBS yield an order of magnitude\nimprovement in energy-efficiency, improves the coverage probability\nsignificantly at low signal to interference and noise (SINR) regime.\n
