چکیده

In this paper, an efficient reservation-based handoff control scheme is proposed for improving bandwidth utilization in multimedia mobile cellular networks. In the proposed scheme, the network reserves resources for handoff traffic based on both the probabilities of a call moving into its neighboring cells and the traffic loading distributions in those neighbors. An analytical model is developed to obtain the performance bounds of the proposed scheme. The simulation results indicate that by the proposed scheme, an increase in bandwidth utilization is achieved, while maintaining low call dropping probabilities for real-time calls under different traffic load distributions.

An adaptive bandwidth reservation scheme for 4G cellular networks using flexible 2-tier cell structure

Many mechanisms based on bandwidth reservation have been proposed in the literature to decrease connection dropping probability for handoffs in cellular communications. The handoff events occur at a much higher rate in packet-switched fourth generation mobile communication networks than in traditional cellular systems. An efficient bandwidth reservation mechanism for the neighboring cells is th...

Resource Management Scheme Based on Position and Direction for Handoff Control in Micro/Pico-Cellular Networks

We propose a handoff control scheme to accommodate mobile multimedia traffic based on the resource reservation procedure using the direction estimation. This proposed scheme uses a novel mobile tracking method based on Fuzzy Multi-Criteria Decision Making (FMCDM), in which uncertain parameters such as Pilot Signal Strength (PSS), the distances between the Mobile Terminal (MT) and the Base Stati...

A Cell-based Call Admission Control and Bandwidth Reservation Scheme for QoS Support in Wireless Cellular Networks

The deployment of multimedia services in wireless cellular networks calls for network resource management strategies for providing Quality-of-Service (QoS) support to mobile users. An important issue in wireless QoS provisioning is the prevention of handoff drops. We develop a cell-based call admission control (CAC) and bandwidth reservation scheme that aims at minimizing the handoff dropping p...
