A tool has been designed to simulate broadband satellite communication systems and techniques: a system and protocol simulator based on advanced DVB-RCS and DVB-S2 standards. As a powerful and flexible tool, it can be used to investigate and optimize current and future satellite communication systems, mainly to develop resource management algorithms and assess system performances. It is capable of...
Adaptive resource allocation for multimedia quality of service (QoS) support in broadband wireless network is examined in this work. A service model consisting of three classes with different handoff dropping requirements is presented. Appropriate call admission control and resource reservation schemes are developed to allocate resource adaptively to the real time service classes with stringent delay...
To achieve a successful broadband wireless access solution, the IEEE 802.16 subcommittee has released a series of standards for WiMAX (worldwide interoperability for microwave access). From a technical viewpoint, WiMAX is a feasible alternative to the wired Internet access solutions such as cable modem and DSL. Nevertheless, from the commercial viewpoint, whether the promise of WiMAX will be materialized...
Call admission control (CAC) strategies for multimedia traffic in wireless mobile networks are considered. Particularly, a wireless cell serving two types of customers; narrowband (n-type) which require 1 channel and wideband (w-type) which require bwges1 channels is studied. New and handoff calls of both types are modeled. System performance is obtained by solving the resulting stochastic matrices...
