Modeling epidemic data diffusion for wireless mobile networks

Abstract

Data/content dissemination among the mobile devices is the fundamental building block for all the applications in wireless mobile collaborative computing, known as mobile peer‐to‐peer. Different parameters such as node density, scheduling among neighboring nodes, mobility pattern, and node speed have a tremendous impact on data diffusion in a mobile peer‐to‐peer environment. In this paper, we develop analytical models for object diffusion time/delay in a wireless mobile network to apprehend the complex interrelationship among these different parameters. In the analysis, we calculate the probabilities of transmitting a single object from one node to multiple nodes using the epidemic model of spread of disease. We also incorporate the impact of node mobility, radio range, and node density in the networks into the analysis. Utilizing these transition probabilities, we estimate the expected delay for diffusing an object to the entire network both for single object and multiple object scenarios. We then calculate the transmission probabilities of multiple objects among the nodes in the wireless mobile network considering network dynamics. Through extensive simulations, we demonstrate that the proposed scheme is efficient for data diffusion in the wireless mobile network. Copyright © 2012 John Wiley & Sons, Ltd.

Energy-efficient information dissemination based on received signal strength in wireless sensor networks

“…There have been previous studies on analyzing the information dissemination in wireless networks [8][9][10][11]. For example, in [8,9], the authors analyzed the throughput and the delay for the information dissemination in wireless ad-hoc networks.…”

“…Using their models, they showed the relation between the information delivery ratio and the time for the dissemination. In [11], the authors analyzed an epidemic model process in wireless mobile networks and derived the time for diffusing the message to the entire network. However, in [8][9][10][11], they focused on the process of data diffusion and they did not address energy efficiency.…”

Deactivation-controlled epidemic routing in disruption tolerant networks with multiple sinks

“…Various epidemic routing protocols and analytical models have been proposed in [1]- [3], [5], [6], [14], [15]. We notice that they always assume the pairwise inter-meeting time between mobile nodes is known.…”

“…The Random Direction Mobility (RDM) [17] is considered as a general and widely adopted mobility model [1], [5], [8], [15], [18]. Initially, any mobile node chooses its direction independently with an angle uniformly distributed within [0, 2π), and then travels along that direction.…”
