Treemap-Based Burst Mapping Algorithm for Downlink Mobile WiMAX Systems

Free registration required

Executive Summary

This paper presents the authors' sqTM burst mapping algorithm for downlink Mobile WiMAX systems. Based on a treemap visualization algorithm, they introduce a new burst mapping scheme they called sqTM, greatly reducing the amount of wasted slots. They obtained between 60% and 75% reduction compared to some reference algorithms they implemented. These limited wastes are able to provide better cell throughput and larger cell capacities. Unfortunately, sqTM is significantly slower than reference algorithms, but still easily coping with 5 ms frames.
