Resource Management Schemes in Wireless Networks: Modelling and Analysis of Handoff Schemes and Resource Re-Allocation in Homogeneous and Heterogeneous Cellular Networks

Over recent years, wireless communication systems have been experiencing a dramatic and continuous growth in the number of subscribers, thus placing extra demands on system capacity. At the same time, keeping Quality of Service (QoS) at an acceptable level is a critical concern and a challenge to the wireless network designer. In this sense, performance analysis must be the first step in designing or improving a network. A good modelling and analysis of the wireless cellular networks will lead to a high level of QoS. In this book, different analytical models of various handoff schemes and resource re-allocation in homogeneous and heterogeneous wireless cellular networks are developed and investigated. The sustained increase in users and the request for advanced services are some of the key motivations for considering the designing of Hierarchical Cellular Networks (HCN). In HCN, calls blocked in a microcell flow over to an overlay macrocell. Microcells can be replaced by WLANs as this can provide high bandwidth and its users have limited mobility features. Efficient sharing of resources between wireless cellular networks and WLANs will improve the capacity as well as QoS metrics.
