Abstract
A device for computing a routing path from a source node to a destination node across a 6TISCH mesh network comprising a plurality of nodes, the device comprising: an interface for communicating with one or more nodes in the network; a memory configured to store data regarding the stability and availability of individual nodes in said network to receive packet data; a controller configured to: employ said data regarding the stability and availability of individual nodes in said network to receive packet data to calculate a path stability metric for each of a plurality of potential routing paths between said source node and said destination node, employ said path stability metric to select one of said plurality of potential routing paths for data transmission between said source node and said destination node, and cause said interface to transmit a signal configured to cause said plurality of nodes to transmit data from said source node to said destination node via said selected route.
