The effect of critical transmission range in epidemic data propagation for mobile ad-hoc social network

In this paper, we study the information dissemination in mobile ad-hoc network, where mobile nodes are randomly and independently distributed with a given density on a square. Nodes in network move following a random direction mobility (RDM) model. One piece of information is disseminated from source to all other nodes in the network, utilizing the basic epidemic routing protocol. We develop an analytical model based on Ordinary Differential Equation (ODE) approach, in which we take the transmission range as the critical and intuitive system parameter instead of pair-wise meeting rate. Typically, we proceed to study the impacts of overlap among the moving informed nodes on the percolation ratio and the delivery delay. The analytical mode is verified by simulations. This research captures the characteristics of information disseminated in mobile ad-hoc network.
