- Abstract
- We analyze the actual condition of wireless resource environment for AIS system used in maritime communication, and propose a method to detect malfunctioning wireless communication device. When an AIS system is transmitted in a manner incompatible with the slot timing due to malfunction, the AIS wireless apparatus of the Carrier Sense Time Division Multiple Access (CSTDMA) scheme can communicate but the usable slot available becomes smaller and the AIS wireless apparatus of the Self Organized Time Division Multiple Access (SOTDMA) scheme may fail to receive an AIS message due to transmission data collision on the wireless. Through the analysis of the experimental results, it was confirmed that a large number of malfunctioning AIS radio devices are actually transmitting at the actual sea. In this paper, we propose a method to improve the performance of the maritime wireless communication by improving the wireless interference environment due to malfunctioning transponder by finding out the malfunctioning AIS wireless communication device and compensating or removing it to secure the occupied slot by erroneous operation.
