“…In other words, how robust RANDI is as the 802.11 channel quality deteriorates, due to, for example, the interference of Bluetooth communication [10]. For this purpose we artificially introduced environmental noise to the SWANS system and tested RANDI under a wide range of bit error rates (from 10 -9 to 10 -3 ).…”

“…Shoemake [46] performed coexistence testing and showed that interference results in considerable throughput loss. Punnoose et al [57] identified that effective bandwidth degrades more rapidly than the packet loss rate owing to deferred transmissions caused by carrier sensing in WiFi. In contrast, Bluetooth performance starts to degrade rapidly when the interfering WiFi signal is comparable to the desired signal level since Bluetooth does not use "carrier sensing."…”

Abstract-Using handheld devices such as cellular phones and smart phones for personal entertainment has become commonplace in today's lifestyle. Virtually all of these devices are equipped with Bluetooth technology that can be used to distribute entertainment contents such as music and movie clips. Mobile users can download content from the opportunistically available infrastructure (e.g., Digital Billboards) as well as direct Peer-toPeer (P2P) collaboration which significantly increases content availability/coverage. P2P content distribution protocol design is heavily influenced by the characteristics of Bluetooth, which is the main departure from Internet-based content distribution. However, little has been done to understand the performance of overall Bluetooth operations, ranging from peer discovery to data downloading, in dynamic environments with mobility, interference, and different Bluetooth versions/chipsets. In this paper, we first perform extensive experiments to measure the performance of Bluetooth in dynamic environments. We find that Bluetooth-based content distribution faces several challenges such as time/energy consuming resource discovery and limited bandwidth even with the enhanced features of the latest Bluetooth version. We then propose strategies that can effectively improve the performance of resource discovery and downloading phases. Our simulation and experimental results document the improvements obtained with our proposed techniques.

Abstract-Streaming audio has become a popular form of media on the Internet. As wireless personal area network architectures (e.g. Bluetooth) are now targeted to support multimedia traffic, streaming audio over these technologies will give rise to interesting applications. But, the variable nature of the wireless medium will not lend itself easily to supporting audio streaming. In this paper we focus on Bluetooth and propose an enhancement to the Bluetooth link layer ARQ mechanism to compensate for channel degradation and to better support audio streaming. Specifically, our scheme adaptively sets the ARQ timeout value based on current channel conditions. We show through simulation and testbed experiments that the adaptive ARQ improves the streaming quality significantly compared to the "vanilla" link layer of Bluetooth, especially in noisy environments. Our proposed approach is simple to implement and can actually be extended to the link layer of any wireless technologies.
