Joint pushing and proactive caching holds the promise of significantly increasing the throughput and decreasing the latency of content-centric wireless networks. In this work, we import the pushing and caching mechanism into a traditional packet-oriented network for decreasing the average queueing delay. Since the decreasing relies on extra costs paid for the pushing-caching mechanism, such as the...
Proactively pushing content to users is a promising way of coping with the explosively growing traffic demand of next-generation mobile networks. However, it is unclear whether content pushing can improve the energy efficiency of delay-constrained wireless communication systems over fading channels. With pushing, the energy consumption can be reduced due to the extended transmission time duration...
Wireless communication system is expected to provide service with low latency and high energy efficiency. To improve the energy efficiency, the transceiver prefers sending packets, when the channel states are good. However, such opportunistic transmission may induce undesirably large latency. Therefore, a fundamental tradeoff exists between the average transmission power and average queuing delay,...
