关键业务网络中基于记忆的自适应MAC协议

Adaptive MAC Protocols Using Memory for Networks with Critical Traffic

Jaeok Park, Mihaela van der Schaar

摘要:

我们考虑无线通信网络,其中网络用户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,用户需要尽早发送关键流量。然而,大多数现有的媒体访问控制(MAC)协议不足以满足用户的数据传输的迫切需要与关键业务。在本文中,我们设计了一类分布式MAC协议,实现协调使用有限长度的内存中的用户包含自己的意见和流量类型。我们制定了一个协议设计问题,并找到解决问题的最佳协议。我们表明,所提出的协议,使用户的关键业务传输的关键业务没有中断,从其他用户经过短暂的延迟,同时允许用户有效地共享信道时,没有关键的流量。此外,所提出的协议需要较短的内存,可以实现没有显式的消息传递。

英文摘要:

We consider 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 critical traffic as early as possible. However, most existing medium access control (MAC) protocols are not adequate to meet the urgent need for data transmission by users with critical traffic. In this paper, we devise a class of distributed MAC protocols that achieve coordination using the finite-length memory of users containing their own observations and traffic types. We formulate a protocol design problem and find optimal protocols that solve the problem. We show that the proposed protocols enable a user with critical traffic to transmit its critical traffic without interruption from other users after a short delay while allowing users to share the channel efficiently when there is no critical traffic. Moreover, the proposed protocols require short memory and can be implemented without explicit message passing.
