随机接入网络中的任务感知媒体接入控制

Mission-Aware Medium Access Control in Random Access Networks

Jaeok Park, Mihaela van der Schaar

摘要:

我们研究无线通信网络中的关键任务网络,其中网络用户会受到紧急情况和危机等关键事件的影响。如果用户发生关键事件,用户需要尽早发送必要的信息以寻求帮助。然而,大多数现有的媒体访问控制(MAC)协议不足以满足紧急情况下用户对信息传输的迫切需求。在这篇论文中,我们提出了一类新的MAC协议,利用现有的过去的信息以及当前的信息。我们提出的协议是任务感知的,因为他们规定不同的传输决策规则,在不同的情况下,用户。我们表明,所提出的协议执行良好,不仅当系统面临着一个关键的情况下,而且当没有关键的情况。通过利用过去的信息,所提出的协议协调用户的传输,以实现高吞吐量在正常阶段的操作,并让用户在一个关键的情况下,使成功的传输,而它是在关键的情况。此外,所提出的协议需要较短的存储器和没有消息交换。

英文摘要:

We study mission-critical networking in wireless communication networks, where network users are subject to critical events such as emergencies and crises. If a critical event occurs to a user, the user needs to send necessary information for help as early as possible. However, most existing medium access control (MAC) protocols are not adequate to meet the urgent need for information transmission by users in a critical situation. In this paer, we propose a novel class of MAC protocols that utilize available past information as well as current information. Our proposed protocols are mission-aware since they prescribe different transmission decision rules to users in different situations. We show that the proposed protocols perform well not only when the system faces a critical situation but also when there is no critical situation. By utilizing past information, the proposed protocols coordinate transmissions by users to achieve high throughput in the normal phase of operation and to let a user in a critical situation make successful transmissions while it is in the critical situation. Moreover, the proposed protocols require short memory and no message exchanges.
