Resource allocation in wireless networks

Resource allocation in wireless networks

Wireless services are one of the strongest growth areas in telecommunications today. Dynamic channel allocation schemes have garnered a considerable amount of attention as methods for achieving efficient use of system resources. Various combinations of permanent channel assignment, channel borrowing, shared pools of channels, channel ordering, channel reassignment, and dynamic adjustment of par...

Asymptotic Close to Optimal Resource Allocation in Centralized Multi-band Wireless Networks

This paper concerns sub-channel allocation in multi-user wireless networks with a view to increasing the network throughput. It is assumed there are some sub-channels to be equally divided among active links, such that the total sum rate increases, where it is assumed each link is subject to a maximum transmit power constraint. This problem is found to be a non-convex optimization problem and i...

Bicriteria Resource Allocation Problem in Pert Networks

We develop a bicriteria model for the resource allocation problem in PERT networks, in which the total direct costs of the project as the first objective, and the mean of project completion time as the second objective are minimized. The activity durations are assumed to be independent random variables with either exponential or Erlang distributions, in which the mean of each activity duration ...

Dynamic Resource Allocation in Wireless Networks

In this thesis we investigate different algorithms for dynamic resource allocation in wireless networks. We introduce a general framework for modeling systems which is applicable to many scenarios. We also analyze a specific scenario with adaptive beamforming and show how it fits into the proposed framework. We then study two different resource allocation problems: Quality-of-Service (QoS) cons...
