A linear regression based cell reselection approach for selecting destination base station during handover in wimax

Worldwide Interoperability for Microwave Access (WiMAX) specified by IEEE 802.12 supports Wireless Metropolitan Area Network (WMAN). It is one of the most prominent technology for the next generation networks and it provides high data rates and long range with full support of mobility. It is based on IEEE 802.16 standards and the modifications specifying the MAC and physical layers for fixed, portable, nomadic and mobile access. The aim of the WiMAX Forum Network Working Group is to provide controlled transition of the Mobile Station (MS) between Base Stations (BSs) without the loss of data. In this paper, an enrichment of a Cell Reselection approach is introduced for selecting the Destination Base Station (DBS). Here, the Selection of Destination Base Station Algorithm (SDBS) is proposed to select the targeted (destination) BS. The proposed method uses the Linear Regression Model (LRM) to formulate a hard handover algorithm to predict the Received Signal Strength Indicator (RSSI) value. The value is broadcasted in order to trigger the scanning process. The performance of the proposed SDBS algorithm is compared with the existing technique without using the Linear Regression Model. The proposed SDBS algorithm provideslesser handover time, handover latency with better network throughput and bandwidth consumption ratio than the existing approach.
