Unified video-on-demand (UVoD) is a recently proposed architecture that integrates multicast transmission with unicast transmission to improve system efficiency. Streaming channels in a UVoD system are divided into unicast and multicast channels, with the multicast channels further divided equally among all videos. This uniform channel-allocation scheme is simple to design and implement, but th...

Voice services over Adaptive Multi-user channels on One Slot (VAMOS) has been standardized as an extension to the Global System for Mobile Communications (GSM). The aim of VAMOS is to increase the capacity of GSM, while maintaining backward compatibility with the legacy system. To this end, the Orthogonal Sub-channels (OSC) concept is employed, where two Gaussian minimum-shift keying (GMSK) sig...

Based on the GSM radio architecture, general packet radio service (GPRS) provides users data connections with variable data rates and high bandwidth efficiency. In GPRS service, allocation of physical channels is flexible, i.e., multiple channels can be allocated to a user. In this paper, we propose four algorithms for the GPRS radio resource allocation: fixed resource allocation (FRA), dynamic...

In this work, we investigate the performance of distributed admission control with QoS provisioning and dynamical channel allocation for mobile/wireless networks, where co-channel reuse distance is considered as the only limiting factor to channel sharing. We first provide a QoS metric feasible for admission control with dynamically allocated channels. We then derive a criterion analytically us...

This paper presents a c omparison of channel allocation schemes for mobile c ellular networks. Three schemes have been evaluated: Fixed Channel Allocation (FCA), Dynamic Channel Allocation (DCA) and Channel Allocation with Space a nd Time Variations (CA STV). The third scheme uses information about mobile users profiles for getting adaptability to traffic fluctuations. Results were obtained u s...

This paper presents a fast and efficient contiguous allocation strategy for 3D mesh multicomputers, referred to as Turning Busy List (TBL for short), which can identify a free sub-mesh of the requested size as long as it exists in the mesh system. Turning means that the orientation of the allocation request is changed when no sub-mesh is available in the requested orientation. The TBL strategy ...

We consider an i.i.d. state-dependent channel with partial (rate limited) channel state information (CSI) at the transmitter (CSIT) and full CSI at the receiver (CSIR). The CSIT comprises a non-causal rate limited part, which is communicated by a third party (a genie) over a way-side channel, and may also include outputs of a deterministic scalar quantizer of the state. A single letter expressi...
