Latest advances in Wavelength Division Multiplexing (WDM) technology make it possible to build all-optical transparent networks, which are considered to be able to satisfy the rapidly growing capacity demand. However, in a transparent WDM network the optical signal transmitted from a source to a destination node might be degraded due to physical layer impairments induced by transmission through...

This paper presents a problem of queuing theoretic performance modeling and analysis of Orthogonal Frequency Division Multiple Access (OFDMA) under broad-band wireless networks. We consider a single-cell WiMAX environment in which the base station allocates sub channels to the subscriber stations in its coverage area. The sub channels allocated to a subscriber station are shared by multiple con...

Connection Admission Control (CAC) in an ATM network is the set of actions taken by the network at connection set-up (or during call re-negotiation) in order to establish whether a (virtual channel/virtual path) connection can be accepted or rejected. A connection request is accepted only when sufficient resources are available to establish the call through the whole network at its required Qua...

Wireless ATM, presents several interesting challenges such as managing an end-to-end ATM connection (using connection re-routing) and location management, handling high error rate performance of wireless links, maintaining the ATM cell sequence, and supporting quality of service (QoS) requirement. Recently, the design of re-routing schemes has received some consideration in the literature. Howe...
