Development of bluetooth mesh core stack using omnet++

Laszlo Kajdocsi Andras Dorombozi Janos Kovacs

Publication Name: Sisy 2019 IEEE 17th International Symposium on Intelligent Systems and Informatics Proceedings

Publication Date: 2019-09-01

Volume: Unknown

Issue: Unknown

Page Range: 23-28

Description:

The evolution of networking technologies is crucial in the 21st century. The greatest challenge for the Industry 4.0 is the spread and generalization of cyber physical production systems which cannot evolve without new networking technologies. One of these research areas is the wireless mesh networking which may offer an accurate, fast, adaptive, self-organizing, self-healing and inexpensive solution in communication. Wireless mesh networking involves some radio technologies, like Wi-Fi, ZigBee, Bluetooth, IQRF, etc. The most widespread and cost effective solution of the above mentioned ones is Bluetooth. Luckily, Bluetooth SIG adopted the first mesh core stack into Bluetooth 5 protocol in 2017, although a newer Bluetooth 5.1 came out since then. In this paper, the development of Bluetooth mesh core stack will be presented using OmNET++ simulation tool.

Issue on implementation Possibility of Bluetooth Mesh Capabilities into OmNET++

Description:

Navigation was always important to humankind. Today, it is unimaginable to navigate in the world without the Global Positioning System. Although, the Global Positioning System operates very accurately outdoors but does not in indoor environments. Unfortunately, the indoor navigation is still in its infancy. However, several approaches have been proposed during the last decade but none of them is accurate and/or inexpensive enough for the consumer use. According to the authors' proposal, utilization of a hybrid mesh network might solve the inaccuracy. The mesh technology would offer an accurate, fast, adaptive, self-organizing, self-healing and inexpensive solution for the indoor positioning. A hybrid mesh network would involve some technologies like Wi-Fi, Bluetooth, RFID or IQRF. Fortunately, the Bluetooth Special Interest Group announced the mesh capability in the Bluetooth 5 standard in 2017. However, building up a physical network is always expensive experiment, thus simulations would be executed in a OmNET++. In this paper, the implementation possibility of the Bluetooth mesh capabilities will be analyzed.

Description:

Navigation has always been important to people. Thus, it is hard to succeed in navigation without Global Positioning System. Although, Global Positioning System can be efficiently used in outdoor environments the indoor navigation is still in its infancy. Nevertheless, the indoor navigation is one of many open challenges in the 21st century that affects to the major technological advances. However, several indoor positioning solutions have been built over the last decade, but they are still neither accurate enough nor inexpensive for consumer use. Therefore, this paper proposes a novel suggestion that should have a great potential for applying mesh technology in the indoor navigation systems in order to improve the accuracy and the computational capabilities of devices.

Publication Name: Sisy 2014 IEEE 12th International Symposium on Intelligent Systems and Informatics Proceedings

Publication Date: 2014-10-14

Volume: Unknown

Issue: Unknown

Page Range: 239-244

Description:

This paper describes the current state-of-the-art in Cognitive Architectures, which could assist in the development of the agent-based robotic systems, and gives a proposition for a possibly new model. Agent-based cognitive systems would be the key-factor of the future autonomous mobile robots.
