“…Similarly to other technologies, Bluetooth devices spend most of the energy during data exchange, while the energy consumption decreases when the device is in hold state. As also analyzed in [125], the creation of energy-aware scatternets, able to monitor and reduce energy consumption, is also very important in Bluetooth networks. This aspect has several requirements:…”

In the last years, the Internet of Things (IoT) has emerged as a key application context in the design and evolution of technologies in the transition toward a 5G ecosystem. More and more IoT technologies have entered the market and represent important enablers in the deployment of networks of interconnected devices. As network and spatial device densities grow, energy efficiency and consumption are becoming an important aspect in analyzing the performance and suitability of different technologies. In this framework, this survey presents an extensive review of IoT technologies, including both Low-Power Short-Area Networks (LPSANs) and Low-Power Wide-Area Networks (LPWANs), from the perspective of energy efficiency and power consumption. Existing consumption models and energy efficiency mechanisms are categorized, analyzed and discussed, in order to highlight the main trends proposed in literature and standards toward achieving energy-efficient IoT networks. Current limitations and open challenges are also discussed, aiming at highlighting new possible research directions.

Bluetooth is one of mobile ad hoc network technologies, which allows communication through piconet. A piconet consists of at most eight active devices at the same time. A multiple piconets network is called a scatternet, which is connected through a common node known as a relay. The limited energy available in a Bluetooth-enabled device is a critical issue for the mobile devices to participate effectively in the scatternet. Therefore, to improve the network performance, energy capability of a Bluetooth device should be analyzed periodically, and subsequently to determine its role in the network based on this energy analysis. It is expected that the more energy capable device shall perform more demanding role, i.e. the role of a high performance device shall be selected based on its energy level. In this paper, we discussed the design issues of an efficient Dynamic EnergyAware Network Maintenance (DENM) technique. The proposed technique dynamically adapts changes in the network and maintains a constructed scatternet, as well as it ensures network stability and reduces overhead. The simulation results showed that the proposed technique outperformed the existing protocols in term of message overhead, transmission delay, and reconstruction time.

“…However, Scatternet connection increases the average hop length and the number of links connected to a certain node, therefore it decreases capacity [15]. To increase capacity, Scatternet optimization method is needed [14]. Scatternet also has a scalability problem.…”

As Bluetooth is available in most personal and portable terminals (eg, cellular phone, PDA, videocamera, laptop, etc) P2P video streaming through Bluetooth networks is now a reality. Camera equipped Bluetooth phones capture video and broadcast it to other Bluetooth devices and to the infrastructure. Traditionally, large scale Bluetooth networks were designed using scatternet concepts. However, many Bluetooth devices do not support Scatternet connections and, even if they support it, they provide only very limited features suitable mostly for static environments. In high mobility situations, a traditional Scatternet design is not useful because of frequent disconnections and reconnections. To overcome these problems, we propose Overlaid Bluetooth Piconets (OBP) and Simplified Overlaid Bluetooth Piconets (SOBP) that interconnect Piconets forming virtual Scatternets. In OBP, every Piconet dynamically reconfigures to collect metadata from neighboring Piconets. If metadata shows the existence of useful data to transfer, an inter-piconet connection is made to carry out the transfer. SOBP can be used instead of OBP once neighbor piconets have already discovered each other. In this paper, we compare via analysis and simulation the throughput and efficiency of OBP, SOBP and Scatternet for video applications. We demonstrate the feasibility of video over OBP and SOBP for a representative application.
