TLDR
A SIP-based solution for terminal mobility and real-time applications, using SIP and cross-layer interactions to improve the hard HO in WiMAX is proposed.Abstract:
The IEEE 802.16e/WiMAX standards introduced the micro and macro-mobility capabilities as a promising technology. While the procedures for mobility management are defined, the decision on performing the handover is left to the developers. The paper proposes a SIP-based solution for terminal mobility and real-time applications, using SIP and cross-layer interactions to improve the hard HO in WiMAX.read more

Pre-Coordination Mechanism for Fast Handover in WiMAX Networks
TL;DR: A pre-coordination mechanism (PCM) for supporting fast handover in WiMAX networks is proposed by measuring the distance between the BS and the MSS and predicting the time of handover occurs, and thus pre-allocating available resources for handover usages.
