This paper discusses wireless channel allocation problem for data dissemination in mobile computing systems. Methods for accessing data through broadcast and on-demand channels are described. We provide analytical models and cost formulae for the exclusive broadcast channels and the exclusive on-demand channels and propose a dynamic channel allocation algorithm for optimizing system performance...

The needs for run-time data storage in modern wired and wireless network applications are increasing. Additionally, the nature of these applications is very dynamic, resulting in heavy reliance on dynamic memory allocation. The most significant problem in dynamic memory allocation is fragmentation, which can cause the system to run out of memory and crash, if it is left unchecked. The available...

The objective of this thesis is to investigate the initial allocation of pollution permits in a dynamic tradeable market. Tradeable pollution permit markets are an increasingly common method of environmental regulation and it is apparent that future schemes may have a number of repeated compliance periods. It is important to consider how and to what extent the dynamic allocation of pollution pe...

Parallel applications can exhibit different behaviours in their dynamic need of resources. Then, predefined and automatic approaches to allocation cannot always achieve satisfactory results. The paper presents the approach adopted in the PO (Parallel Objects) environment to let users drive object allocation in parallel/distributed architectures. A set of a high-level directives permits users to...

This paper examines the problem of congestion control evaluation in dynamic networks. We determine a source of deficiencies for existing metrics of congestion control performance – the existing metrics are defined with respect to ideal allocations that do not represent short-term efficiency and fairness of network usage in dynamic environments. We introduce the concept of an effair allocation, ...

Advances in network management and switching technologies make dynamic bandwidth allocation of logical networks built on top of a physical network possible. Previous proposed dynamic bandwidth allocation algorithms are based on simplified network model. The analytical model is valid only under restrictive assumptions. Infinitesimal Perturbation Analysis, a technique which estimates the gradient...
