Dynamic MAPT Approach for Vertical Handover Optimization in Heterogeneous Network for CBR and VBR QoS Guarantees

摘要

Efficient handover optimization and intelligent mobility management mechanism are the key requirements for designing next generation wireless network. Therefore, a dynamic Multiple Attribute decision based on Priority of Traffic classes (MAPT) for Constant Bit rate (CBR) and Variable Bit Rate (VBR) are proposed in this paper to optimize the handover operations. The IEEE 802.21 Media Independent Handover (MIH) standard provides an associated service to MAPT for achieving seamless handover. Simulation results prove that the proposed work resourcefully minimizes the vertical handover delay, packet loss, jitter and thus improves the throughput for both real time and non- real time applications.
