Using Content-Centric Networks in IoT Systems

In Internet of Things (IoT) networks, key parameters such as energy efficiency, reliability, high delivery speed, minimal latency, and low message loss are essential. Currently, the BLE technology offers numerous advantages for constructing low-power networks, for which the 6LoWPAN adaptation for IPv6 operation (6LoBLE) was created. Implementing 6LoBLE enables the construction of an energy-efficient network where each device can function both as a regular node (sensor) and as a router. However, the use of CoAP and MQTT protocols has several drawbacks, including significant delays in packet transmission within multi-hop networks. This work explores the application of a Content-Centric Networking (CCN) architecture over BLE. In CCN, each node also acts as a router, allowing for packet forwarding directly to the recipient via the shortest path without relying on a central device. Experiments were conducted on identical devices and network topology to compare the characteristics of CCN and CoAP networks. The tests used OS RIOT modules: ccn-lite and gcoap. The results obtained may contribute to the development of the CCN implementation codebase and the broader application of content-centric network architecture in low-power BLE networks. The work consists of 60 pages, includes 27 figures, 1 appendice, and 26 sources.
