In this paper, we consider the effects on network capacity when the nodes of an ad hoc network are allowed to cooperate. These results are then compared to the theoretical upper bound on the capacity of an ad hoc network without cooperation. For our cooperative model, two or more nodes are grouped together to cooperatively transmit information from the source node to the destination node. Here the...
An architecture is presented for a high speed cellular radio access network based on ATM transport technology. Central to this approach is a new concept known as the virtual connection tree which avoids the need to involve the network call processor for every cell hand-off attempt. Such an approach can readily support a very high rate of hand-offs, thereby enabling use of physically small radio cells...
For multiuser communications networks, lightwave technology offers the potential to supply a pool of capacity — to be shared among users — far above that provided by any alternative technology. However, the bandwidth limitation of the electro-optic converters needed to attach each user to the optical medium prevents any one user from accessing more than a tiny fraction of the overall capacity. This...
The major focus of this paper is the design and control of micro/picocellular wireless access systems supporting non‐real‐time (or data) traffic subject to a guaranteed quality‐of‐service as defined by four metrics: call blocking probability, cell overload probability, average wireless bandwidth available to a mobile terminal, and probability that the available wireless bandwidth per mobile is less...
