Title

Ad hoc Networking with Bluetooth

Abstract

In this paper we explore the ability to support multimedia traffic in indoor, wireless ad hoc PANs (Personal Area Networks) using the Bluetooth technology. We first define the representative ad hoc networking applications such as wireless access to the Internet, document distribution, videoconferencing, webcasting, interaction with sensors and actuators, etc. For such applications, we define the performance requirements placed on the PAN. There are two technologies now competing for the PAN market: the IEEE 802.11 “legacy” technology, and the newly introduced Bluetooth technology. By IEEE 802.11, we refer to the operation of 802.11 in the DCF mode, which is the mode implemented in the commercial WaveLAN cards. In the rest of the paper, we will use the term WaveLAN to refer to 802.11 in its DCF mode. We will attempt to answer the questions: how effective is the Bluetooth technology in supporting collaborative, “virtual ad hoc networking” applications and how does it compare with WaveLAN? To answer these questions, we have developed an NS-2 model of Bluetooth. We have also developed models of adaptive applications such as voice and video. For WaveLAN, we have used the existing NS-2 models. The results show that Bluetooth provides better support for real-time applications as compared to WaveLAN. It does not exhibit the “capture” behavior observed, for example, in WaveLAN. Also, with the addition of nodes to the “indoor” space, it adds to the total “system” capacity and gives a better overall throughput.
