Abstract
A method of allocating time slots for sensor node sample transmission from sensor nodes in a wireless sensor node network which forms part of a control system for controlling an industrial process includes receiving a sample from a first sensor node in a first time slot of a superframe, which first sample has a value outside an accepted range of values, obtaining an identification of a second time slot of the superframe in which second time slot the first sensor node is to send a further sample in a subsequent superframe, and providing instructions to the first sensor node to send the further sample in the second time slot of a subsequent superframe. A computer program product and a sensor node network interface system are also disclosed herein.
