In this paper, we develop a comprehensive analytical framework for cellular networks that are enhanced with coordinated device-to-device (D2D) communication, where the D2D devices are equipped with content caching capabilities. The base station (BS) coordinates the D2D communication by establishing a D2D link between the requesting user and the nearest D2D helper within the same cell if the latter...
In this letter, we introduce the concept of cloud empowered heterogeneous networks. We propose a simple yet efficient association mechanism for the selection of a serving remote radio head (RRH) for a desired mobile user (MU). We introduce the concept of user centric clustering which improves the user throughput by contributing on several fronts. Employing well established tools from stochastic geometry,...
Coordinated multi-point (CoMP) transmission has been considered in the multi-cell, multi-user system in the downlink where each remote radio equipment (RRE) unit transmits data stream(s) to all the user(s) in the CoMP system. CoMP transmission has been shown to improve the performance of the cell-edge users but the associated problem of high data and feedback overhead as well as complexity is still...
We consider the problem of distributed detection in wireless sensor networks. The sensors are randomly deployed according to a Poisson point process. The received power of the signal emanating form an intruding target is assumed to follow the inverse power law. We propose the real-time counting rule (rt-CR) detector to endow the system with real-time detection delay capabilities. We show that the...
