Improvement of mobility management for IEEE 802 21 networks with enhanced E2TX and DSR flow using NS2

Abstract

In multi technology-enabled terminals most of the resources have become available in the Internet. Such multi-mode terminals have new challenges to mobility management in IEEE 802.21. The major objective of IEEE 802.21 is to allow handovers among heterogeneous technologies which consists of IEEE 802 and cellular technologies deprived of service interruption, therefore enhancing the user experience of mobile terminals. Considerable functionality is essential to offer session continuity relying on complex interactions with purpose of specific toward each particular technology. In order to address some of these challenges in the newlinenetwork, the IEEE is mainly working on a new specification on mediaindependent newlinehandover services (IEEE 802.21 MIH). The main aim of these specifications is to improve user experience of mobile terminals by enabling handovers between heterogeneous technologies while optimizing session continuity. The IEEE 802.21 MIH is purely focused on handover easier between various wireless networks in newlineheterogeneous environment. There are already several techniques are being used for the improvement of mobility management such as handover technique with vertical and horizontal part. However Horizontal handover which is between different cells of the same network .The vertical handover which is between different types of networks. newline newline
