Research paper thumbnail of Efficient relay node management method for BLE MESH networks

The Bluetooth Low Energy (BLE) MESH network technology gains popularity in low duty IoT systems. ... more The Bluetooth Low Energy (BLE) MESH network technology gains popularity in low duty IoT systems. Its advantage is a low energy consumption that enables long lifetime of IoT systems. The paper proposes and evaluates new MRT management methods, i.e. exact and heuristic, that improves energy efficiency of BLE MESH network by minimizing the number of active relay nodes. The performed experiments confirm efficiency of the MRT methods resulting in significantly lower energy consumption of BLE MESH network.

The AQUILA architecture enhances the DiffServ concept [A Conceptual Model for DiffServ Routers (2000), An Architecture for Differentiated Services (1998), An Expedited Forwarding PHB (2001)] by adding new functionality for admission control and resource management as well as by defining new set of Network Services (NSs). Each NS is optimised for specific type of traffic (e.g. reactive and nonreactive) and has its own traffic handling mechanisms. The mentioned mechanisms operate at different time scales, ranging from longmedium term resources management (provisioning, resource pools) to flow level admission control, down to packet level scheduling and queuing management. Some of these mechanisms are related to NSs: in particular each NS is associated to a set of traffic handling algorithms at flow and packet level, collectively referred to as Traffic Classes (TCLs). This paper describes the set of traffic handling mechanisms defined in AQUILA, with a special focus on the implementation of TCLs, both at packet and flow level. In particular the scheduling/queuing and admission control schemes for each TCL are presented. Exemplary measurement results verifying the effectiveness of AQUILA approach for providing Quality of Service (QoS) guarantees and QoS differentiation are also included.
