Mac the Mac System : a Progress Report

The notion of machine-aided cognition implies an intimate collaboration between a human user and a computer in a real-time dialogue on the solution of a problem, in which the two parties contribute their best capabilities. In order for this intimate collaboration to be possible, a computer system is needed that can serve simultaneously a large number of people, and that is easily accessible to ...

IA-MAC: Interference Aware MAC for WLANs

Among the numerous standards for wireless communications, the IEEE 802.11 Wireless Local Area Network is the one with the highest utilization at the moment. The 802.11 has been devised explicitly for low mobility, single access point scenario, so its effectiveness can be limited when it is utilized both in ad hoc mode and with multiple access points. Many research has been done and is still ong...

MAC Reforgeability

Message Authentication Codes (MACs) are a central algorithm deployed in virtually every security protocol in common usage. The integrity and authenticity of messages relies entirely on the security of the MAC; we examine cases in which this security is lost. In this paper, we examine the notion of “reforgeability” for MACs. We first give a definition for this new notion, then examine some of th...

. Introduction 2. Medium Access Control (mac) 2.1. Mac Protocol Structure

Broadband and mobile communications are presently the two major drivers in the telecommunications industry. Asynchronous Transfer Mode (ATM) is considered the most suitable transport technique for the Broadband Integrated Services Digital Network (B-ISDN), due to its ability to flexibly support a wide range of services with Quality-of-Service (QoS) guarantees. These services are categorized in ...
