The Three-Tier Spectrum Sharing Framework (3-TSF) is a spectrum sharing model adopted by the Federal Communications Commission which operates in the 3.5 GHz spectrum band. According to this model, under-utilized federal ...

Scarcity of the wireless spectrum has become a major problem as a result of the rapid growth in wireless communications. With the proliferation of smart phones and tablets, wireless data more than doubles every year. The ...

We formulate the problem of as a non-convex, non-linear mixed-integer program. We prove that it is NP-Hard under both multicast/unicast modes of server transmission -- even when the caches have a large capacity and storage ...

Second, we characterize the average end-to-end delay in an opportunistic multi-hop ad-hoc secondary network overlaid with a primary multi-hop ad-hoc network, both with and without cooperation between the two networks. ...

In this thesis, the problem of video caching across a set of small-cell base stations (SBS) in edge-caching cellular networks is considered. The SBSs are connected to each other over a high-capacity short-delay back-haul ...

Reliable communication in wireless networks currently relies on the perfect estimation of the varying state of the wireless channel at all communicating nodes. While the next generation of wireless networks promises ...
