Embodiment Construction

[0029] The invention relates to a network comprising a plurality of communication nodes. In an example of the invention, the network includes various applications linked to different services. Thanks to the embodiments of the invention described below, different services can reuse the infrastructure while maintaining logical isolation between them.

[0030] By way of illustration, embodiments of the invention which will now be described are aimed at the various following objectives.

[0031] The first aspect addressed by these embodiments is the security of the network. As an example, the IEEE 802.15.4 security sublayer provides basic network security for other communication protocols. It is aimed at protecting against a wide range of cyber threats and situations that cause a network to fail or provide defective service that prevents it from functioning properly. In addition to the network security provided by the 6LoWPAN network security mechanism that ensures network-wide...

Abstract

The invention relates to a method of a communication node communicating in a network comprising a plurality of nodes, said nodes belonging to at least one virtual network, wherein the method comprises the communication node identifying whether a first data packet belongs to said virtual network based on at least one of: - a cryptographic key used for the data packet; - a cryptographic key identifier present in the first data packet; - a Personal Area Network identifier present in the first data packet; or the combination of a cryptographic key and a sender IP address used for the first data packet.

Description

technical field [0001] The invention relates to a method for communicating in a network, in particular a wireless network. [0002] The invention is for example relevant to outdoor lighting networks, where multiple networks co-exist and share the same medium and protocols. Background technique [0003] In a network, in particular in an outdoor lighting network, multiple networks dedicated to different services may coexist. [0004] Consider here for example using such as figure 1 Constrained network of the depicted 6LoWPAN protocol stack. In this exemplary protocol stack described according to the OSI model, layer 1, the physical layer is based on the 802.15.4 PHY, and layer 2, the data layer includes the 802.15.4 MAC and 802.15.4 security sublayers. In this example, routing is performed at layer 3 using the RPL or MPL protocol. [0005] Such networks can be deployed at scale, i.e., city-wide Internet of Things (IoT) deployments used in smart city contexts or in smart bu...
