Benefits of technology

The patent text describes a wireless communication system and a method to select different roles within the system. This system and method improve the adaptability of wireless communication. Overall, the technical effects of this invention make wireless communication more flexible and efficient.

Problems solved by technology

One drawback of the prior art solution is that it does not address the local availability of the active devices around the mesh network, e.g. in case new terminals would like to join the network (but are in the radio coverage of super-saving terminals only).
Additionally, updating all router information from central node can cause extensive signalling especially when number of nodes is high.

Embodiment Construction

[0025]FIG. 1 illustrates an example wireless communication network 100, which may be e.g. a wireless mesh network (WMN). The WMN may be e.g. a wireless sensor network (WSN). The wireless communication in the network 100 may be based on e.g. Bluetooth Low Energy (BLE), IEEE 802.15 standard, IEEE 802.11 standard, or other radio protocol.

[0026]The network 100 may comprise a plurality of radio nodes. The plurality of nodes may be able to operate in different roles. The network comprises at least one node operating in a sink role 102, i.e. it is part of gateway to other networks, e.g. Internet, and delivering data in and from the network 100. The rest of the nodes of the plurality of nodes may be divided into router nodes 104 and non-router nodes 106 depending on if they need to participate in data forwarding. The operation as a router node 104 comprises capability for receiving data from at least one other node and transmitting the received data to at least one other node. The router no...

Abstract

A role selection method, a radio node device, and a wireless communication system, where the wireless communication system includes a plurality of radio nodes, each of the plurality of radio nodes being able to operate at least as a router node or as a non-router node; each of the plurality of radio nodes being configured to detect density of the router nodes within its neighbourhood, and make a decision based on the detected density whether to operate as a router node or as a non-router node.

Description

TECHNICAL FIELD[0001]The invention concerns in general the technical field of wireless communication networks. Especially the invention concerns role selection of nodes in wireless communication networks.BACKGROUND OF THE INVENTION[0002]Wireless communication networks, e.g. wireless mesh networks, are composed of multiple, even hundreds or thousands of radio nodes (later referred as “nodes”) that communicate with each other over two or more radio interfaces. To support the various functions of such wireless communication networks, the nodes typically need to operate in different roles. One or more nodes of the network operate in sink role, i.e. they are part of gateways to other networks, e.g. Internet, and deliver data in and from the wireless communication network.[0003]The rest of the nodes of the network may be divided into routers and non-routers depending on if they need to participate in data forwarding. Routers maintain the connectivity of the network and forward data of oth...
