Higher Adaptability of the Airport Body Scanner
Higher Adaptability of the Airport Body Scanner

The amount of connections is the main factor affecting the scalability of advanced airport security baggage scanners and the difference between the real and the simulation scanning situations may not be large enough to have the impact on the x ray baggage machine performance. At the same time, the round trip time of the airport body scanners can be measured as well as randomly selected with the cloud based machine. As a result, the average trip time is less than ninety milliseconds and the trip time connection packets can be sent in interval that equals to the delays in some cases. In practice, there may be multiple scanning tasks that need to be executed at the same time, which means that the airport body scanners need to use multiple threading to handle the scanning connections. In order to cope with the multiple scanning tasks in parallel, multiple scanning orders need to be launched at the same time by controlling the number of threads and recording the execution time. It is important to mention that the bandwidth of the airport body scanners is mainly determined by the general frequencies of packet sending and receiving so that any increase in the frequency would lead to the identification of the scanning task and the filtering of a large part of the scanning packets, which means that bandwidth is likely to become the bottleneck of advanced baggage x ray scanner performance. What is more, it can be seen that with the growth of the scanning connections or scanning scale, the task execution time is on the increase in a linear manner and the average execution time is longer in comparison to the models with less connections.

However, this ratio does not grow in proportion to the scanning scale so it would be hardly possible for X-ray baggage Inspection system to have a relatively high scalability if the number of connections is limited. On the other hand, if this problem can be solved with the integration of the cloud computing functions, the destination port of the airport body scanners can be combined into one server so as to lessen the burden of the entire system. Different testing environments have been used to detect the performance of the airport body scanners and prove that the machines are not only functional and scalable but also very practical in security scanning application. In the future, the adaptability of the advanced airport body scanners will be further improved so that they can be well tuned to the sensed situation. The coordination between the X-ray baggage security scanner and the other parts of the system also needs to be strengthened so that the data sending speed can be adjusted in accordance with the relaying speed.
