Simulator for Resource Allocation in Future Mobile Networks

ID: LiTH-IDA-Ex-02/99

Resource allocation in mobile networks can be done with bandwidth as the limiting resource, but also other types of resources could be subject to optimization, e.g. radio power or CPU capacity. This thesis aims to develop a simulator for evaluating resource allocation algorithms in mobile networks. After doing a limited study of free network simulation environments, JavaSim is proposed as the base for the simulator. On top of this, the nodes of the mobile network are modelled and implemented. Traffic models defined in earlier work on mobile networks are used to generate traffic in the network. In order to evaluate the resulting platform two different resource allocation algorithms are implemented and plugged into the simulator. One of them, the Rate-Based Borrowing Scheme has previously known characteristics. These are compared to reconstructed results from the simulator. The comparison shows similar results, but the results of the simulations are consistently poorer than the original ones. This is probably due to some differences in the implementation of the algorithm. A second algorithm, Time-aware Resource Allocation, is implemented to show that the simulator is flexible enough to handle different types of algorithms. Execution time and memory consumption increase linearly as the number of simulated nodes grows. With some modification the simulator can do resource allocation based on resources other than bandwidth, for example CPU capacity.

Keywords: 3G, RNC, simulator, resource allocation, traffic modelling
