In this paper we study quality-of-service (QoS) provisioning in an ad hoc cognitive radio network with spectrum underlay. Both streaming traffic and non-real-time (nrt) data traffic are considered. An admission control scheme is first proposed based on relatively static information such as path loss and average interference levels in order to guarantee the average throughput of each connection. Outage...
In this paper, we present an admission control mechanism for video streaming driven by service provider (SP) over P2P networks. SP-driven P2P network is a network in which service provider has a comprehensive control over contracted resources utilisation. SP assures the coordination and the creation of overlay P2P network and it is responsible for admission control and resource allocation among others...
Allocations of physical transmission rate, sub-carrier, and power in MC-CDMA systems are proposed to minimize total uplink power consumptions for users of different data rate and bit-error-rate (BER) requirements with the receiver using linear minimum-mean-square-error (LMMSE) MUD. Based on multi-code (MC) and variable-spreading-length (VSL) strategies for multi-rate transmissions, we derive the discrete-rate...
