Abstract
The IVEF (Inter-VTS Data Exchange Format) service is the draft standard designed for exchange of information on sea traffic between the vessel traffic systems and between the vessels. Standardization of this service is under way as a part of the next-generation navigation system, called e-Navigation. The International Association of Lighthouse Authorities (IALA) suggests, on its recommendation V-145, the IVEF service model and the protocol for provisioning of this service. But the detailed configuration of this service must be designed by the users. This paper suggests, based on the basic service model and protocol provided in the recommendation V-145, the implementation of the VTS (Vessel Traffic Service) middleware which will facilitate exchange of information on sea traffic. This paper developed a system enabling IVEF service simulation under a wireless environment made possible by improving IVEF SDK, which is an open source. For this, a mobile phone loaded with Android platform and desk top PC have been used for emulation of a ship on voyage and VTS center.

1. Introduction
e-Navigation, which was introduced in 2005 for safe vessel navigation, has prompted IALA [1-2] to standardize e-Navigation through IT convergence. Objective of e-Navigation, which is being led by IMO (International Maritime Organization), is to support data exchange, convergence and analysis between vessels and with onshore control center, thereby maximize safety, security on sea and protect maritime environment. Vessel Traffic Service Center relies on navigation support equipment such as radar and ECIDS (Electronic Chart Display and Information System) and VHF audio communication to monitor any risk of collision or gathers information on collision or stranding to ensure safe entry of vessels to coastal waters and prevent accidents. But, the time from identifying a risk situation to evasion flight takes long and the procedures are complicated, too. This is supported by the fact that 30% of maritime accidents are caused by collision out of which over 90% is associated with human error. This raises the need to apply IT-driven next-generation maritime traffic control system to both vessels and VTSC and to develop a distinct technology that can replace the existing VTS [3].
