On Information Dissemination in Infrastructure-Based Mobile Ad-Hoc Networks

In this paper, the authors consider 2D wireless multi-hop networks with mobile nodes randomly distributed on a torus, and a small number of base stations (infrastructure nodes) deterministically placed in the same area. Mobile nodes move following a random walk mobility model. A piece of information is broadcast from the base stations at the same time in a multi-hop manner using a Susceptible-Infectious-Recovered (SIR) epidemic routing algorithm. A distinguishing feature of the SIR algorithm, which leverages the mobility of mobile users, is that a relay node carries a piece of information for a pre-determined amount of time and forwards it at any available opportunity during that time.
