Human Mobility Model in Mission-oriented Opportunistic Networks

Abstract

Mission-oriented opportunistic networks are an emerging network form, which takes the completion of a specific mission as the application background and mission-oriented mobility is its prominent feature. In this paper, we first analyze some basic characteristics of human activity behavior in the mission-oriented opportunistic network, thereby constructing a multi-dimensional mobility metric space, which is divided into individuality metrics, pairwise encounter metrics, and group metrics to describe the characteristics of human mobility. Then, we propose a novel mission-oriented human mobility model, which calculates the node movement trajectory through the human mission, the mobile characteristic finite set, and the node trajectory generator. The experimental results show that our mobility model not only shows the obvious purpose of human movement, but also shows more human mobility characteristics than the random waypoint mobility model, and obtains simulation results closer to the real trajectory.
