Dynamic energy-aware network maintenance for bluetooth

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 Energy-Aware 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.
