항만 컨테이너 이동성 모델

A port, where tens of thousands of containers are stored and forwarded each day, is an ideal site to which the ubiquitous communication infrastructure can be established to enhance the throughput. To design a communication protocol for ubiquitous sensor networks which monitors containers in a port, we need a mobility model for the containers. However, most prior mobility models target the movement of humans or vehicles in spaces such as a campus or a theme park. There is no suitable model for containers in a port yard. In this work, we first propose a method of simulating the movement of containers in a port yard based on the analysis on the port operations such as, imports, exports, and intra-port transports. Then we propose a general mobility model which can be applied to ports with different scales and infrastructures. This general model is validated by comparing to simulation results.
