“…Figure 4 summarizes the results, which show that the bluetooth 1.1 allows transmitting a 4MB song in 132 seconds with a data transfer rate that is around 250kbps, and the bluetooth 2.0 needs 91 seconds with a data transfer rate around 350 kbps. Note that the connection setup time is not shown and hence one second should be added to the downloading time due to connection set-up time (Frank Kargl and Weber, 2002).…”

Abstract:Despite the increasing number of e-music downloads and the large use of mobile devices, the mobile music market is slowly taking off. Prices seem to be the main burden: compared to the wired environment, a song is twice or three times more expensive. Furthermore, mobile network transfer data rate causes the download time to be very long. In this paper we propose Bluemusic, a multi channel architecture that couples the usage of the mobile phone network with the free-of-charge communication technologies provided in cellphones (e.g., bluetooth or Wi-Fi) to distribute music in the mobile environment. To protect digital contents, Bluemusic is provided with a security mechanism that prevents illegal contents distribution. An evaluation of our approach shows that Bluemusic can be helpful to the expansion of the mobile music market.

“…Therefore, we need solutions that encompass networking and application issues involved in realizing mobile and ubiquitous access to the services. Several research groups are proposing frameworks for developing applications over Bluetooth-based networks (for instance, [5] and [6]) and evaluate the possibility of using this technology for building ad-hoc networks suitable for dedicated applications, such as voice transmission [7], audio streaming [8], context-aware applications [9], and Internet access point [10].…”

Over the last years, technology evolution is leading the way towards autonomous, ubiquitous and widespread interactions among small computing devices. To this aim, communication technologies that support dynamicity and mobility and work on inexpensive small devices have attracted much attention. The Bluetooth specification particularly fits this idea, providing a free, versatile, and flexible wireless network technology with low power consumption. On the other hand, as the degree of penetration of computational services has increased in everyday life, users' habits have deeply changed, resulting into an increasing request for mobile and ubiquitous services. In a few years, most of the devices accessing the web services will be mobile. Therefore, we need solutions that encompass networking and application issues involved in realizing mobile and ubiquitous access to the services. In this paper, we analyze how Bluetooth can be used to design, develop, and deploy Web Services-based applications that run on mobile devices. We propose and evaluate a framework that allows the interaction with Web Services from mobile devices using Bluetooth as communication channel.

“…There are some attempts at either developing new algorithms, or at customizing the existing algorithms for Bluetooth based ad hoc networks. Kargl et al proposed Bluetooth Scatternet Routing (BSR) [11], which is a reactive routing protocol similar to AODV or DSR but keeps additional information on the state of links. The authors proposed a cross layer optimization (between link, and network layer) to shorten the connection set-up delay.…”

Abstract. This paper focuses on the impact of topology on Bluetooth personal area network. We first present some observations on performance degradations of Bluetooth PAN due to network topologies, and then analyze its reason. Based on our analysis, we propose a flexible scatternet formation algorithm under conference scenario for multi-hop communication. By using proposed method, scatternet can be formed flexibly with different topologies under a controlled way. To utilize topology information in multi-hop communication, we propose a new link metric Load Metric(LM) information in multi-hop communication, we propose a new link metric Load Metric(LM) instead of number of hops. LM is derived from estimation of nodes' link bandwidth, which reflects different roles of nodes in Bluetooth scatternet. This proposal helps routing protocol to bypass heavily loaded nodes, and find route with larger bandwidth. We present some experimental results based on implementation, which prove the effectiveness of our protocols.
