In this paper, we study the delay-constrained message delivery capacity formulation in mobile wireless networks. The message delivery capacity specifies the maximum percentage of messages that can be successfully delivered to base stations within a given time constraint. By taking full advantage of node mobility and rendezvous during mobile node encounter, messages can be delivered to a base station...
A novel scheme of soft-handoff in CDMA system based on a distributed management technology named mobile agent is promoted in this letter. In this method, a mobile agent, which can get channels bandwidth utilization and signal strength information automatically among Base Stations (BSs) and Mobile Switch Centers (MSCs), is created in each BS and MSC. The soft-handoff would be managed by BSs instead...
One of the most important issues in offering real-time communication services in a mobile environment is support for seamless handover between base stations during a communication session. In Mobile WiMAX, a mobile station may have to perform a scan and association process before handover, but unfortunately, this scan and association process introduces service disruption. In this letter, we investigate...
