Delay Analysis of an Improved Wimax Macro-Femto Handover Technique and Cell Selection Algorithm

Femtocells (FC) have been introduced in WiMAX networks due to the high data rate broadband access provided by Wimax networks. The key features like increased cell coverage, high throughput indoors and system capacity of FC are widely being accepted. However, issues regarding macro/femto handover decision are still being considered. This paper evaluates a technique for a macro/femto handover. The analyzed procedure offers communication with the mobile station having reduced delay. Moreover, it minimizes the number of FC(s) to be scanned during cell selection on the basis of cell ratio thus saving handover decision time.
