Modeling efficient dynamic channel assignment schemes for quality of service wireless multimedia telecommunications through an extended and integrated Java simulation framework

The increasing number of cellular users and the demand for broadband mobile communications (3rd and 4th generation) raises the problem of bandwidth availability and the associated channel allocation strategies. Moreover, Quality of Service (QoS) is the challenge for such modern wireless multimedia telecommunications. This paper presents new algorithms for efficient bandwidth management of GSM cellular multimedia systems. Besides, it proposes a comprehensive simulation system for evaluating channel assignment schemes in QoS multimedia cellular systems incorporating their principles, entities and concepts involved. The proposed system is implemented in Java, in order to create an educational generic simulation environment with the future capability of internetworking. The system is designed with the goal to be efficient in simulating large scale generic cellular multimedia telecommunication systems.
