Towards a clustering based data diffusion protocol in delay tolerant networks
In Delay Tolerant Networks (DTN), diffusion protocols can benefit from the users’ mobility in order to reach some distant nodes. However, existing protocols like flooding present a rather high overhead because of redundant transmissions. The main contribution of this paper is to introduce a new diffusion protocol, called CBD (Clustering Based data Diffusion). Our solution provides to each node the possibility to adapt its diffusion strategy on-the-fly for a more efficient diffusion by evaluating its local density. We show through the use of a real measurements mobility that CBD brings an improvement in forwarding performances, in terms of delivery ratio, delay and the amount of generated messages.
