IPv6 over Bluetooth Low Energy (6LoBLE) can realize the seamless connection between Bluetooth Low Energy (BLE) devices and the Internet, solve the restrictions on Bluetooth applications as short distance communication solutions, and advance the development of applications of smart cities, such as smart buildings and smart city management. Since neighbor discovery is the first step for BLE devices to establish a connection with each other, this paper proposes a novel neighbor discovery protocol for IPv6 over BLE mesh networks, including the structure of IPv6 over BLE mesh networks, the networking solutions, and IPv6 address auto-configuration and update mechanism. Furthermore, we analyze and simulate the performance of the neighbor discovery protocol utilizing the Revierbed simulator, and the results show the effectiveness of the proposed neighbor discovery protocol even in a crowded environment.

Bluetooth Low Energy (BLE) Mesh Networks enable flexible and reliable communications for low-power Internet of Things (IoT) devices. Most BLE-based mesh protocols are implemented as overlays on top of the standard Bluetooth star topologies while using piconets and scatternets. Nonetheless, mesh topology support has increased the vulnerability of BLE to security threats, since a larger number of devices can participate in a BLE Mesh network. To address these concerns, BLE version 5 enhanced existing BLE security features to deal with various authenticity, integrity, and confidentiality issues. Despite of the BLE version 5 security enhancements, viable IDS solutions for BLE Mesh networks remain a nascent research area.

Neighbor Discovery Protocol

The neighbor discovery protocol (NDP) is a stateless protocol facilitating link local communication in IPv6 networks. The nodes employ IPv6 NDP to locate other hosts/routers on the link, cover resolution of link layer addresses, duplicate address detections and track reachability status about paths to active nodes. However, link local communication using NDP is susceptible to some severe attacks, which if neglected leave the network vulnerable. Attackers can spoof source addresses of legitimate nodes by forging NDP messages and propel attacks like Denial of Service (DoS) and Man-in-the-Middle (MITM) leading to failure of IPv6 host initialization. To avert this, RFC 3971 advocates employing Secure Neighbor Discovery (SeND) to make the process inviolable. SeND fortifies message tampering, prevents IPv6 address theft, including protection against replay attacks and enable validation of routers on the link. Although SeND is a robust link layer security mechanism, its practical implementation is reported to have serious shortcomings like cryptographic algorithms which impact computational complexity including bandwidth utilization, as such negate their implementation and adoption. Moreover, the protocol itself fails to provide the confidentiality factor in the network. SeND also falls short of mature unabridged implementations in commercial operating systems and network devices. This paper revisits the protocol implementation and reviews its deployment challenges. This article also discusses some feasible proposals and recommendations for facilitating practical deployment of SeND in IPv6 networks including resource constrained devices like mobile phones.
