Sensor Networking Software and Architectures
Published in John R. Vacca, Handbook of Sensor Networking, 2015
The 6LoWPAN working group in the Internet Engineering Task Force (IETF) created a standard for transmitting IPv6 (Internet protocol version 6) over low-power and lossy networks (LLNs) based on IEEE 802.15.4. 6LoWPAN is described mainly in RFC 4919, RFC 4944, and RFC 6282. The main functionality of 6LoWPAN consists of the LoWPAN adaptation layer, which allows for the compression of IPv6 and related headers such as UDP, totaling 60 bytes, down to just 7 bytes, and optimizing mechanisms for wireless embedded networking (Shelby and Bormann 2009). The LoWPAN header consists of a dispatch value identifying the type of header, followed by an IPv6 header compression byte indicating which fields are compressed, and then any in-line IPv6 fields. An example of 6LoWPAN compression is given in Figure 15.5. In the upper packet, a 1-byte LoWPAN dispatch value (L) is included to indicate full IPv6 over IEEE 802.15.4. The lower packet is an example of 6LoWPAN/UDP in its simplest form with a dispatch value and IPv6 header compression, all IPv6 fields compressed, then followed by a UDP next-header compression byte with compressed source and destination port fields and the UDP checksum (4 bytes).

uIP has the network frameworks as 6LoWPAN. 6LoWPAN open standard was defined by IETF to address the need of wide address space required by IP-driven connected devices that can only be provided by IPv6. 6LoWPAN is an acronym of IPv6 over Low-Power Wireless Personal Area Networks. IETF developed this standard to make IPv6 to be used in low power and lossy networks that are based on IEEE 802.15.4. 6LoWPAN contains an adaptation layer that allows IPv6 packets can be carried out through IEEE 802.15.4 link layer frames.

6LowPAN: This is a low-power Internet Protocol version 6 (IPv6)-based technology for packet delivery in Wireless Personal Area Networks. 6LowPAN allows low-power devices with limited processing power to be connected over The Internet. It supports both 16-bit short and IEEE 64-bit addresses. Further, 6LowPAN is capable of handling a large number of devices deployed in the ad-hoc form. The main application areas of 6LowPAN are low-power radio communication technologies, smart grid, and M2M applications [13].
A Novel Approach for Enhanced Network Formation in 6TiSCH-based IoT Low-Power and Lossy Networks
Published in IETE Journal of Research, 2023
IPv6 over Low Power Wireless Personal Area Network (6LoWPAN) is a wireless protocol designed for the IoT-LLN devices to enable the transmission of IPv6 packets over low-power wireless links. This 6LoWPAN uses a mesh network topology, allowing devices to communicate with each other in a peer-to-peer fashion without needing a central server. The Internet Engineering Task Force (IETF) developed IPv6 over TSCH Mode of IEEE 802.15.4e (6TiSCH) protocol. The 6TiSCH integrates the Internet Protocol (IP) layer over the Time Slotted Channel Hopping (TSCH) link layer of IEEE 802.15.4e in the IoT [1]. IoT applications, including smart homes, smart cities, and industrial automation, use the 6TiSCH. It provides a low-cost, low-power, and scalable solution for connecting many IoT devices reliably and efficiently.
DewCityGame: Dew Computing-based 5G IoT for Smart City Using Coalition Formation Game
Published in IETE Journal of Research, 2022
M2M communication is an important architecture for industrial IoT. In Ref. [14], the authors have proposed a fog computing architecture based on an IoT and M2M communication, where they transmitted the generated data directly to the nearest fog device rather than directly to the cloud. If the amount of data is too large, they get the job done through the cloud. As a result of being done through a nearby fog, the amount of latency generated in the network is much less. IPv6 over low power wireless personal area network (6LoWPAN) is the first protocol that directly connects nodes of one machine to another through IPv6 connectivity, which is very important for wireless networks. In Ref. [15], the authors have discussed in detail the cloud computing architecture for M2M communication based on software-defined networks and network function virtualization. Through this network program, the simplicity increases a lot. The method of allocating resources to solve the major problems of M2M communication based on affinity propagation is discussed in Ref. [16]. In this article, similar machines come together to form a small group. The machines located within the group communicate with each other through the group head via channels. The purpose of the authors in this article is to reduce the delay and operation complexity by increasing the network throughput and system complexity.

The IoT system also uses the Internet to connect a large number of “Things.” Internet protocol (IP) is a universal standard for data communication over heterogeneous networks. Each “Thing” is assigned a unique IP address. As the number of “Things” connected to the internet is increasing rapidly, scalability of the protocol has emerged as a major challenge. Currently, IPv4 is the 32-bit address system that is on the verge of being incapacitated, i.e., using up all the IP addresses. IPv6 is the new 128-bit address system that has a capacity of approximately 2128, or 3.4 × 1038 addresses (Levin and Schmidt, 2014). IPv6 enables every IoT “Thing” to have a unique IP address in the global Internet network. 6LowPAN is a key IPv6-based technology that defines encapsulation and header compression mechanisms independent of the frequency band and physical layers (Wang et al., 2016). In other words, 6LowPAN can be used across different communication platforms (e.g., WiFi, ZigBee, 802.15.4), thereby enabling sensors in heterogeneous networks to carry IPv6 packets and become a part of large-scale IoT system.
