Bluetooth and IEEE 802.11 Wireless Protocols: A Survey and a Comparison

Bluetooth and IEEE 802.11 are two communication protocol standards which define a physical layer and a MAC layer for wireless communications within a short range (from a few meters up to a hundred meters) with low power consumption (from less than 1 mW up to a hundred mW). Bluetooth is oriented to connecting close devices, serving as a substitute for cables, while IEEE 802.11 is oriented towards computer-tocomputer connections, as an extension of or a substitution for cabled LANs. In this paper we offer an overview of these popular wireless communication standards, comparing their main features and behaviors in terms of various metrics, including capacity, network topology, quality of service support, and power consumption

gA Traffic Generator for Testing Communication Systems: Presentation, Implementation and Performance

This paper presents a multi-application traffic generator (MTG), aimed at the generation of packets over a LAN. The generated traffic simulates the one produced by a number of both isochronous and anisochronous applications, thus allowing the measurement of a number of parameters relevant to the communication network. From a test point of view, data generated by the MTG system is equivalent to data generated by real applications spread over a LAN
