Optimum dynamic channel allocation in certain street microcellular radio systems

[1992 Proceedings] Vehicular Technology Society 42nd VTS Conference - Frontiers of Technology, 2000

Examples of such areas are roads and streets where the microcells will form one-dimensional structures. Using smaller cells implies that the variations in telephone traffic load will increase. To adapt to these variations, a simple dynamic channel allocation algorithm for one-dimensional cellular

Performance analysis of DCA-schemes in highway cellular radio systems

As a performance measure, the assignment failure rate is used. It is defined as the relative number of calls not assigned a channel at some instant in time. A lower bound on the assignment failure rate is derived as a function of the call traffic load in a one-dimensional cellular

Performance bounds for power control supported DCA-algorithms in highway micro cellular radio systems

The focus of the paper is on performance bounds of a cellular radio system using dynamic channel assignment (DCA) combined with power control (PC). A trivial upper bound on the performance is identified. The

The system is studied at a randomly chosen instant in time. At the studied instant, the number of not-served terminals for the radio resource allocation scheme under investigation. The expected fraction of terminals that is not served will be used as a performance measure. All results in the

ABSTRACT

On The Spatial Capacity Of Slotted Packet Radio Networks With Capture

Proceedings. 1991 IEEE International Symposium on Information Theory, 2000

Some new bounds on the spatial capacity of Poission random packet radio networks are derived. For... more Some new bounds on the spatial capacity of Poission random packet radio networks are derived. For the special case of linear networks we derive a closed form expression for the upper bound of the capacity as well as a constructive lower bound. For the case of planar networks a new upper bound is presented. Multihop packet radio allows for wide area coverage without an existing infrastructure of base stations. In these networks the capture property of most modulation schemes permits the reception of a packet from a node close by even in the presence of other more distant transmissions. The channel may thus be reused spatially which may allow several transmissions to take place simultaneously [l]. Several explicit access and routing algorithms have been proposed for multihop packet radio systems [3,4].
