In order to support multiple types of service with different QoS requirements in heterogeneous wireless networks, efficient resource management, call admission control strategies, and mobility management are important issues. In this paper, we propose Bandwidth Management Strategy 1 (BMS1), Bandwidth Management Strategy 2 (BMS2) and reservation scheme with fuzzy controller for real-time services....
In this paper, we describe a XML based profile for modeling the semantics of real time systems. We aim to use Real Time Markup Language (RTML) to provide a comprehensive description of temporal properties for the use in distributed systems communication. RTML is derived from a number of specifications including OMG UML Profile in Schedulability, Performance, and Time. In this paper, we discuss the...
The integration of different IP-based wireless networks, such as WiMAX and WiFi, becomes a 2-tier heterogeneous wireless networks is a more and more popular issue. In order to support multiple types of service with different QoS requirements in heterogeneous wireless networks, efficient resource management, call admission control strategies, mobility management and overflow handoff call are important...
The quality of service (QoS) will not be maintained when a communication link failed in a network. In order to assure reliable QoS requirements, a scheme to automatically reroute label switched paths is needed in MPLS network when communication links or routers failed. The time to recover a failed path is important to support the QoS guarantees by quickly rerouting connection. The objective of this...
