Limiting the interest-packet forwarding in information-centric wireless mesh networks

This paper proposes three mechanisms in order to reduce the broadcast storm problem in information-centric wireless mesh networks. The first one defines a probability to forward interest packets. The second one limits the number of interest packets forwarded based on the number of previous forwarding actions of these packets. The third one is a hybrid approach that combines the forwarding criteria of the two previous mechanisms. The performance of a information-centric wireless mesh networks is evaluated with the three proposed mechanisms and also with the default forwarding mechanism. The performance of such network is also compared with the one provided by a wireless mesh network based on the TCP/IP stack running the OLSR protocol. Results show the proposed mechanisms provide a delivery rate four times higher than the one provided by OLSR. In addition, our proposals outperform the default forwarding mechanism by up to 19% in terms of data delivery rate in dense scenarios with high number of hops between source and destination.
