WIRELESS SIMULATION AND SELF-ORGANIZING SPECTRUM MANAGEMENT

Wireless service providers are continually looking for new features an d products to improve quality of service, increase system capacity, an d reduce administrative overhead. The simulation tool W provides a fle xible platform for the exploration of a broad range of system-level de sign and performance issues in wireless networks. investigation of net work issues using W gives Lucent Technologies the ability to design ne w features and products more effectively by reducing development inter vals and implementing a one-pass design on field-quality products. We describe the scope of the simulation platform and illustrate the speci fic use of the W tool for examination of a next-generation channel ass ignment algorithm currently under development. The algorithm's adaptiv e nature provides automatic configuration at system initialization, as well as adaptation to system expansion and traffic patterns with spat ial or temporal variations, thus ensuring ease of operation for servic e providers. initial simulation experiments confirm its self-organizin g capability and suggest a significant improvement in quality of servi ce in terms of call blocking and dropping.
