Abstract:
Delay/Disruption/Disconnection Tolerant Networks (DTNs) attract a great deal of attention as the part of the evolution of various telecommunications networks. In DTNs, the desired features of communication are high-speed data-transfer, high rate of transmission, and reduction of terminal resource usage (e.g., network bandwidth or capacity of node storage). These features often conflict with each other. Although balancing conflicting requirements are important, optimum methodology is still not established. In order to address these issues, we propose a new method which propagates information based on the context of messages in the shared network, such as Vehicle-to-Vehicle (V2V) communication. In our method, we use two parameters, namely, rate of dissemination and maximum number of hops, to control the speed of information propagation and total amount of information in the network. We found that rate of dissemination controls the speed of spreading information and an amount of messages needed for spreading, while maximum number of hops controls the speed of spreading information and the information volume sent per time unit.
