Abstract:
1. A method for communication of multiple sensor nodes in a sensor network comprising: a receiving node prompting other sensor nodes to transmit sensor data to the receiving node by transmitting at least one synchronization telegram, for which the receiving node switches to receive for a time period, in order to receive telegrams from at least one sensor node of the other sensor nodes, where the time period is subdivided into multiple time intervals, and a probability that a given sensor node transmits a telegram in a specific time interval being a function of at least one predefinable parameter and being different from an uniform distribution of the probability for all participating sensor nodes, thus providing random accumulations of transmitted telegrams so that collisions occur in specific time intervals of the time period and at least one sensor node of all participating sensor nodes will transmit its telegram with a higher probability than at least another sensor node of all participating sensor nodes in a given time interval.
