A mesh network comprising an originator station and a target station wherein each station comprises a controller and memory for storing a first path table for storing one or more paths to be used for sending data packets and a second path table for storing one or more alternative paths for sending data packets. The originator station is configured to broadcast a path request data packet for the target station and receive a first path reply data packet comprising a first alternative path to the target station. Then the originator station is further configured to store the first alternative path in the second path table of the originator station and receive at least one second path reply data packet comprising at least one second alternative path to the target station. Then the originator station is further configured to retrieve a best path, based on one or more signal parameters pertaining to each path, to the target station from the second path table of the originator station, store the best path to the target station in the first path table of the originator station and use the best path for sending data packets to target station. An originator station, an intermediate station and a target station in a mesh network is also disclosed. As well is a method of a station in a mesh network and a computer program product.

Mesh path selection

A station () for use in a mesh network comprising at least one first station () and a second station () wherein the station comprises a controller () configured to receive a path request for a path from the first station () to the second station (); determine a proposed path between the first station () and the second station (); and determine a cost for the proposed path, wherein the controller () is characterized in that it is configured to retrieve a number of jumps and a bit rate, and to include the number of jumps and a bit rate in the determination of the cost for the proposed path, wherein an increase in number of jumps and/or decrease in bit rate leads to an increase in cost for the proposed path.

Path finding in a mesh network with adaptive bitrate

An arrangement of a mesh network comprising a first station, a second station and one or more intermediate stations is disclosed. The first, second and one or more intermediate stations are configured to comprise a sleep mode wherein the first, second and one or more intermediate stations are idle, and an awake mode wherein the first, second and one or more intermediate stations are awake. The first, second and one or more intermediate stations are further configured to be in the awake mode during a duration of a discovery window&#x2014;DW&#x2014;and a mesh management window&#x2014;MMW&#x2014;and wherein first, second and one or more intermediate stations are configured to listen for a synchronization beacon during the DW and to transmit and/or listen for zero or more mesh path hybrid wireless mesh protocol&#x2014;HWMP&#x2014;frames during the MMW. A method of the arrangement, as well as a first station, an intermediate station, a second station, a method for a first station, a method for an intermediate station and a method for a second station is also disclosed.
