The mismatch between user demand and service supply creates a congestion in mobile wireless networks. The literature has a strong evidence that user behavior is highly predictable. Taking advantage of user demand predictability allows the carrier to apply proactive caching in order to smooth out the network load. Moreover, harnessing the information about user mobility enhances carrier's caching decision...
Transitional Region Phenomenon leads to the existence of lossy links in wireless networks, which results in a transmission between two users who are theoretically connected under the Deterministic Network Model cannot be guaranteed. Therefore, we focus on a more practical network model - Probabilistic Network Model (PNM) which can better characterize the lossy links in wireless networks. To be specific,...
This work studies the problems of feedback allocation and scheduling for a multichannel downlink cellular network under limited and delayed feedback. We consider a realistic scenario where a fixed and small number of link states can be reported to the base- station (BS) per time-slot. We study the trade- off between knowing at the BS a small number of accurate link states (i.e. that can be...
To meet the ever-increasing demands on higher throughput and better network delay performance, 60 GHZ networking is proposed as a promising solution for the next generation of wireless communications. To successfully deploy such networks, its important to understand their performance first. However, due to the unique fading characteristic of the 60 GHz channel, the characterization of the corresponding...
Information-centric network technique is developed to reduce duplicate transmissions for popular data contents by adopting caching strategy and enabling mobile users to access popular data contents from cache stations of nearby network gateways. In current information-centric wireless networks, one popular data content can be stored in multiple cache stations and requested by multiple mobile users...
