Using the theory of Poisson cluster process (PCP), this paper provides a framework to
analyze multi-cell uplink non-orthogonal multiple access (NOMA) systems. Specifically, we …

Base station (BS) sleeping has emerged as a viable solution to enhance the overall network
energy efficiency by inactivating the underutilized BSs. However, it affects the performance …

This paper investigates the physical-layer security of uplink non-orthogonal multiple access
(NOMA) in the cellular Internet of Things (IoT) with invoking stochastic geometry. Poisson …

This paper presents a novel framework to derive the statistics of the interference considering
dedicated and shared spectrum access for uplink transmission in two-tier small cell networks …

The dense deployment of high and low power nodes, ie, eNodeBs (eNBs) and small cells
(SCs), respectively, is expected to be the core element of fifth generation (5G) networks …

Due to highly variant traffic in downlink (DL) and uplink (UL) in heterogeneous networks
(HetNets), dynamic time-division duplexing (TDD) is proposed to dynamically allocate UL …

Tiered networks have been introduced to mitigate the issues related to poor cellular
coverage in dead zones and indoor environments. However, the large-scale deployment of …

In recent years, the explosion of data traffic usage in wireless industry has resulted in a trend
of hyper-dense small cells. With the large scale deployment of small cells, the rising cost of …

This paper presents a geometrically based method for the calculation of the node-to-node
distance distribution function in circular-shaped networks. In our approach, this function is …

The performance of a wireless network is related to the Euclidean distance distribution
between the communication nodes, which in turn depends on network geometry. In this …
