Resource Management In Integrated Cellular Networks

Abstract

ABSTRACT newlinePresent wireless communication systems are required to support a variety of high-speed data communication services for its users, such as video streaming and cloud-based services. As the users demands for such services grow, more efficient wireless systems need to be designed that can support high-speed data and, at the same time, serve users in a fair manner. This objective could be achieved by using efficient resource allocation schemes at the transmitters of the wireless communication systems. As the number of available channels in a cell is limited, users could be faced with call terminations whenever traffic in the cell is high, and as a result they could be blocked by the cell completely. As the demand for mobile communication has grown remarkably in the past few years, mobile communication networks should be able to utilize the limited resources in an efficient and a convenient manner. The radio frequency spectrum that is currently available is limited in nature and thus can no longer be counted on to support the ever increasing number of mobile users demand. As a result, the required Quality of Service (QoS) is no longer attainable until an optimum solution is obtained. newlineThis thesis analyzes four things, namely, resource (bandwidth) allocation, improving network performance by improving the utility function, reducing call blocking probability, and optimizing resources efficiently. One of the challenges that they pose, is to allocate resource that would be in a position to support multiple traffic that include voice, video and data. Even though a lot of resource allocation schemes have been proposed, they mostly tend to focus on different ways to support multiple traffic in a single mode of network, or they concentrate on various schemes to support a single mode of traffic in an integrated heterogeneous wireless and mobile network. Therefore, they may not be suitable for supporting multiple traffic in an integrated heterogeneous wireless and mobile network. As the general trend has been veering t
