Main Article Content
Abstract
- The IEEE 802.16e (WiMAX) is a broadband wireless technology that supports mobility of mobile station (MS). When the mobile station moves and needs to change the base station. Three handoff methods are supported in IEEE 802.16e standard - Hard Handoff (HHO), Fast Base Station Switching (FBSS) and Macro Diversity Handover (MDHO). In this paper we have proposed a new Macro Diversity Handover mechanism. A new handover mechanism supports Quality of service (QoS) such as Unsolicited grant service (UGS), Extended real-time polling service (ertPS), Real-time polling service (rtPS), Non-real-time polling service (nrtPS) and Best effort (BE). A new handover mechanism reduces handover time more than IEEE 802.16e standard.
