Abstract:
1. A method for multi-hop data transmission in an ad-hoc network with concealed nodes, comprising: determining, at a first node prior to transmitting, a probability of a collision-free data transmission to a next node; and in the case of a high probability of a collision-free data transmission, transmitting, from the first node, a user-data packet to the next node without coordinating, via the next node, with concealed nodes disposed in a vicinity of the next node regarding the data transmission to the next node; wherein a time characteristic of an average data-transmission volume between the next node and every concealed node is registered, and wherein the first node transmits the user-data packet to the next node, without coordinating with the concealed nodes, in periodically-occurring time slots with a relatively-lower average data transmission volume.
