Towards Understanding the Compound Behaviour of Periodic and Random Mobility on Data Dissemination
The underlying fundamental aspect that affects routing and data dissemination in mobile networks is the (communication) contact between nodes. If nodes do not have any contact, then any geographical, social or other information a routing algorithm exploits is lost; thus, the time-evolution of contacts between nodes is crucial to data dissemination. In this paper, the authors investigate how mobility affects the available contacts between nodes and, in turn, provide transitive time-ordered multi-hop paths between source-destination nodes in a mobile network. In particular, they consider a simple 1-dimensional network model and compare, through a simulation study, periodic mobility versus random mobility, while also extrapolating between these two extremes.
