This paper proposes a retrial queueing model with the finite number of sources to evaluate
the performance of spectrum renting in mobile cellular networks. The model incorporates …

Owing to its potential to satisfy all outstanding queries for the same data item with a single
response, on-demand data broadcast becomes a widely accepted approach to dynamic and …

Spectrum renting is an operation practice that can be applied to relieve the temporary
capacity shortages of a specific service area in wireless cellular networks. However, works …

Spectrum pooling enables the opportunistic usage of licensed frequency bands for
secondary users during the idle periods of primary users, which can be applied to relieve …

In this paper, we describe a new design procedure for cascaded controller for electrical
drives based on evolutionary algorithms. Most electric drives have two separate controllers …

Nowadays, spectrum renting is a frequently investigated research topic with the aim of
improving the efficiency of spectrum usage in mobile cellular networks. In this paper, we …

Owing to its potential to satisfy all outstanding requests for the same data item with a single
response, on-demand data broadcast becomes a widely accepted approach to dynamic and …

Nowadays, mobile service providers (SPs) have the exclusive access of certain spectrum for
the mobile telecommunication services. This approach may lead to the inefficient use of the …

In this paper, we propose and investigate a spectrum sharing scheme in two cellular
wireless networks. This scheme specifies various considerations of how to share the …

Spectrum renting is a technique for improving the efficiency of spectrum usage and
alleviating the scarcity of the available spectrum in mobile cellular networks. Since the first …
