There are still outbreaks of COVID-19 across the world. Ships increase the risk of worldwide transmission of the virus. Close contact tracing remains as an effective method of reducing the risk of virus transmission. Therefore, close contact tracing in ship environments becomes a research topic. Exposure Notifications API (Application Programming Interface) can be used to determine the encountered location points of close contacts on ships. Location points of close contact are estimated by the encountered location points. Risky areas in ships can be calculated based on the encountered location points. The tracking of close contacts is possible with Bluetooth technology without the Internet. The Bluetooth signal can be used to judge the proximity among detecting devices by using the feature that Bluetooth has a strong signal at close range. This Bluetooth feature makes it possible to trace close contacts in ship environments. In this paper, we propose a method for close contact tracing and showing the risky area in a ship environment by combining beacon and Exposure Notification API using Bluetooth technology. This method does not require an Internet connection for tracing close contacts and can protect the personal information of close contacts.

Hybrid ALOHA is a novel Medium Access Control (MAC) protocol that aims to enhance energy efficiency and packet delivery performance in wireless communication networks. This paper leverages mathematical models and analysis techniques from game theory and Markov chain modeling to investigate the performance of the hybrid ALOHA protocol under cooperative and non-cooperative scenarios. We first evaluate the protocol in a team problem, where all users act cooperatively to optimize the global utility of the system, and then in a non-cooperative game, where each user acts in their own self-interest and aims to access the channel by utilizing a higher retransmission probability, which they believe will optimize their own benefits. The use of Markov chain analysis enables the derivation of analytical expressions for the performance metrics of interest, as well as the determination of optimal and equilibrium retransmission probabilities. Additionally, the game theory approach is used to analyze the distribution of retransmission probabilities in the hybrid ALOHA protocol. Throughout an extensive numerical analysis, we show that the hybrid ALOHA protocol out-performs other ALOHA protocols in terms of all performance metrics, for both cooperative and non-cooperative scenarios. Additionally, we provide insights into the retransmission probabilities that optimize the performance metrics of interest for both scenarios.
