In Wireless Sensor Network (WSN), much attention has been devoted to the energy aware routing and clustering to make the load balanced and the network lifetime longer. The limited energy in battery based sensing as well as the energy hot spot problem because of the unbalanced load in different locations always exist in clustering. Recent studies show that from energy harvest perspective, the network...
Recent studies show that the coded caching technique can facilitate the wireless content distribution, i.e, push the contents into user terminal, by mitigating the wireless traffic volume during the peak-traffic time, where the contents are partially prefetched to the local cache of mobile devices during the off-peak time. The remaining contents are then jointly coded and delivered in multicast, when...
The demands of video traffic transmission have grown rapidly in recent years. The emergence of converged network alleviates heavy burden on cellular network by introducing broadcasting. The transmission cost of contents with large demands can be effectively reduced. The content distribution strategy compromising between broadcasting and unicasting plays an important role in improving the performance...
