A channel allocation algorithm includes a channel acquisition algorithm and a channel selection algorithm. Most of the previous work concentrates on the channel selection algorithm since early channel allocation algorithms simply use a centralized channel acquisition algorithm, which depends on a mobile switching center (MSC) to accomplish channel acquisition. Recently, distributed channel acqu...

Wireless networking is becoming an increasingly important and popular way of providing global information access to users on the move. One of the main challenges for seamless mobility is the availability of simple and robust Channel Allocation algorithm. The radio propagation environment and related handoff challenges are different in cellular structures. A handoff algorithm with fixed paramete...

Dynamic channel resource allocation (DCA) exploiting wideband multiuser diversity can provide data transmission with very high spectral efficiency by scheduling at each dimension (time, frequency, space) the user with the best channel conditions. The main issue arising from this allocation is fairness. Base station or users have to wait until their channel is most favorable to transmit. It is c...

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...

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 provides network designers and operators with simple guidelines on traffic measurements and efficiency evaluation of various channel allocation schemes in digital mobile telecommunications networks. The paper evaluates the efficiency obtained by implementing the following channel allocation schemes: 1) fixed uniform channel allocation (FUCA); 2) fixed nonuniform channel allocation (F...

This work considers the performance of the downlink channel of MIMO cellular networks serving multiple users with different statistical QoS requirements. The paper proposes resource allocation algorithms that aim to optimize the system performance over the sum of the optimal user utility functions by employing the effective capacity theory. Proportionally fair resource allocation among the user...
