Percolation Theory and Large-Scale Wireless Networks: Connectivity, Transmission Delay, and Network

EEB 248ABSTRACT: The mathematical theory of percolation has become a valuable tool for the analysis of large-scale wireless networks deployed in challenging environments. In this talk, we present some recent results on connectivity, transmission delay, and network resilience from a percolation-based perspective.We first study a model for wireless networks where each link in a random geometric graph is active or inactive according to a Markov on-off process. In this case, we show the existence of a phase transition where the dynamic network is either percolated for all time (supercritical) or the network is percolated at no time (subcritical). Due to the dynamic on-off behavior of links, a delay is incurred for information dissemination even when propagation delay is ignored. We show that this transmission delay scales linearly with the Euclidean distance between the sender and the receiver when the network is in the subcritical phase, and the delay scales sub-linearly with the distance if the network is in the supercritical phase. More interestingly, we show that these results can be used to study information dissemination in wireless networks with mobile nodes. Using a new analysis which maps a network of mobile nodes to a network of stationary nodes with dynamic links, we show that messages can be disseminated to all nodes in a mobile network even when the network is not percolated at any fixed instant.Finally, we study the problem of wireless network resilience to node failures from a percolation-based perspective. In practical wireless networks, it is often the case that nodes with larger degrees (i.e., more neighbors) are more likely to fail. We model this phenomenon as a degree-dependent site percolation process on random geometric graphs. We obtain analytical conditions for the existence of phase transitions within this model. Furthermore, in networks carrying traffic load, the failure of one node can result in redistribution of the load onto other nearby nodes. If these nodes fail due to excessive load, then this process can result in cascading failure. We analyze this cascading failure problem, and show that it is equivalent to a degree-dependent site percolation on random geometric graphs. We obtain analytical conditions for cascades in this model.Joint work with Zhenning Kong, Yale University.BIOGRAPHY: Edmund Yeh received his B.S. in Electrical Engineering with Distinction from Stanford University in 1994, his M.Phil in Engineering from the University of Cambridge in 1995, and his Ph.D. in Electrical Engineering and Computer Science from MIT in 2001.

Challenges of a Theoretician / Experimentalist
Fri, Sep 19, 2008 @ 11:30 AM - 01:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Abstract: Theory and experiment are two sides of the research coin, each with its own peculiar challenges, and both necessary for knowledge to advance. Too often, though, theorists and experimenters speak different languages. They fail to understand or appreciate each other's work and how they should fit together. In this seminar, we will discuss some of the important differences between theory and experiment, and we will also talk about how theoretical and experimental research should be kept relevant to each other.Speakers: Profs. Todd Brun and Robert Hellwarth*Pizza will be provided by the EE Department.*
