Seamless handover has become an important challenging issue among research groups over the past 5 years. Researchers and scientists have been making efforts to provide robust and integrated connectivity while the mobile node (MN) moves between networks. Running certain procedures such as movement detection (MD), neighbor discovery (ND), duplicate address detection (DAD) and sending binding updates (Bus) are needed in order to achieve complete handover procedure which results in handover latency and eventually packet loss. Recently, scientists have found that by utilizing information provided by the Global Positioning System (GPS) device, it is possible to reduce the amount of handover latency by decreasing the amount of time consumed by MD, ND and DAD procedures. In this paper we are going to investigate the proposed GPS models and their effects on the handover procedure in the …
