Novel scheme for the distribution of flyers using a real movement model for DTNs

Abstract

In delay tolerant networks (DTNs), simulations used to verify the performance of a routing algorithm usually employ a mobility model, either trace or synthetic. Trace models record the actual movement of individuals in the real world; however, obtaining data can be difficult. Synthetic models use mathematical modelling, which eliminates the need to obtain data from participants; however, this means that the results are not necessarily representative of the actual movement of individuals. This study collected information related to the movement of university students using a specially designed APP featuring location aware and behavior aware functionality. This APP tracks the movement of students in a campus environment and then exports the data for simulation. We also developed a method for the distribution of flyers only to individuals who express an interest in the content of that particular message who can then forward the flyers to others. Simulation results demonstrate that the proposed method is able to enhance the successful delivery ratio while reducing delivery overhead and thereby improve the dissemination of data on campus.
