The global system for mobile communications, (GSM) is the most popular standard that implements second generation (2G) cellular systems. 2G systems combined with general packet radio services (GPRS) (3GPP TS 03.6, 2002) are often described as 2.5G, that is, a technology between the 2G and third generation (3G) of mobile systems. GPRS is a service that provides packet radio access for GSM users....

Wireless technology is creating a revolution in communications. While systems such as broadcast radio and television have been around for many years, many new types of wireless communication systems are emerging such as digital cellular, personal communications services (PCS), and packet radio. Two powerful techniques are usually employed to make communication over wireless mobile fading channe...

The delay characteristics of small IP packets in cellular data networks is investigated through the analysis of the SR-ARQ mechanism. The delay of the radio link controller is taken as the primary delay in the radio access network and all core networking delays are neglected. Results indicate that the average delay may be a misleading measure of system performance for conversational traffic suc...

This paper aims to solve the Radio Resource Management (RRM) problem for Multimedia Broadcast Multicast Service (MBMS) system in cellular network. We develop a flexible model to perform dynamic radio resource allocation for MBMS service by using metaheuristic approach. We conduct fitness landscape analysis to study the characteristics of the proposed model, which helps us to select appropriate ...

Traditional live TV broadcasting systems are proven to be spectrum inefficient. Therefore, researchers propose to provide TV services on 4G LTE networks. However, static broadcast, a typical broadcasting method over cellular network, is inefficient in terms of radio resource usage. To solve this problem, the Audience Driven live TV Scheduling (ADTVS) framework is proposed, to maximize radio res...

This paper presents research on advanced spectrum sharing techniques lead in TRUST and focuses on Radio Access Technologies’ (RATs) joint radio resource management (JRRM). This paper provides details on cellular FDD/TDD JRRM and addresses the different sources of traffic (regular asymmetric and download) to be considered in an SDR context. The TRUST research on impact of software downloads on U...

Dynamic Access Class Barring and Relay Assisted Radio Resource Allocation Methods for Cellular M2M Networks c © Lilatul Ferdouse, 2015 Master of Applied Science Electrical and Computer Engineering Ryerson University Cellular based M2M systems generate massive number of access requests which create congestion in the cellular network. The contention-based random access procedures are designed for...

The primary goal of future cellular mobile communication networks is to provide efficient and cost effective services to mobile users under all environments. The major issues that affects the quality of service and performance in wireless communications systems is scarcity of resources. Hence, efficient resource allocation is prime concern in order to improve the performance of cellular network...

This paper describes a novel self-optimized approach for resource management based on the cognitive radio in the cellular networks. The cognitive radio techniques offer several features like autonomy, sensing and negotiation. The use of cognitive radio approach gives greater autonomy to the base stations in the cellular networks. This autonomy allows an increase in flexibility to deal with new ...
