Abstract
Worldwide, spectrum regulators are reducing the amount of radio spectrum they directly license. Consequently mechanisms are required to permit co-existence of non-cooperative technology. The purpose of this paper is to bring our experiences of this problem to the wireless area, by presenting a simulation system constructed to investigate the effects of imposing various spectrum sharing schemes upon wireless networks operating in the same spectrum band. In particular, wireless metropolitan and local area networks are considered operating in the 5 GHz band using two common sharing schemes—simple frequency hopping and move if interfered, both of which are compared against a spectrum commons approach (free for all). The system’s design and operation is explained, as are the sharing schemes that have been incorporated. Results indicate that significant performance improvements can be obtained compared to a free-for-all approach and that differences occur depending on whether a planned or random frequency allocation is initially used.

Notes
The simulator has the functionality to vary all environment parameters, for example number of sites, number of sectors per site, frequency range, number of channels, number of users.
The current run-time is 12 h for a single simulation run using a mobile Intel Pentium 3.2 GHz with 1 GB RAM running Windows XP version 2002SP2. C++ software complied with Visual Studio version 6.

Appendix
Appendix
This appendix contains the total throughput results of the experiment in Sect. 6 but this time a uniform distribution for traffic generation is used, as against the exponential distribution used to generate the complete set of results. Tables 26, 27, 28, 29, 30, 31 give the total throughput (in percentage terms relative to the spectrum commons result in both networks) under planned channel assignment (Tables 26, 27, 28) and a random assignment (Tables 29, 30, 31). In both cases the conclusions drawn from the experiment which uses the exponential traffic distribution remain valid when compared to the results using the uniform distribution.
