Determining a network route which avoids nodes with a RF-based presence and/or location detection function

Abstract

A system (1) for controlling message routing within a wireless network, which comprises a plurality of nodes (1,11-15), is configured to determine a first subset of the plurality of nodes. The first subset comprises one or more devices (12,15) that are assigned a radio frequency-based presence and/or location detection function. The system is further configured to determine a plurality of routes from a source node (1) to a destination node (12). At least one of the plurality of routes comprises one or more intermediate nodes (11,13,14,15). The system is further configured to select one of the plurality of routes based on how many of the intermediate nodes of each of the plurality of routes are part of the first subset of the plurality of nodes and transmit one or more messages to cause the wireless network to perform message routing according to the selected route.
