Experience versus Talent Shapes the Structure of the Web
Joseph S. Kong, Nima Sarshar, Vwani P. Roychowdhury
We use sequential large-scale crawl data to empirically investigate and validate the dynamics that underlie the evolution of the structure of the web. We find that the overall stru…
Low Latency Wireless Ad-Hoc Networking: Power and Bandwidth Challenges and a Hierarchical Solution
Nima Sarshar, Behnam A. Rezaei, Vwani P. Roychowdhury
This paper is concerned with the scaling of the number of hops in a large scale wireless ad-hoc network (WANET), a quantity we call network latency. A large network latency affects…
Finite Percolation at a Multiple of the Threshold
Nima Sarshar, Patrick Oscar Boykin, Vwani P. Roychowdhury
Bond percolation on infinite heavy-tailed power-law random networks lacks a proper phase transition; or one may say, there is a phase transition at {\em zero percolation probabilit…
A Practical Approach to Joint Network-Source Coding
Nima Sarshar, Xiaolin Wu
We are interested in how to best communicate a real valued source to a number of destinations (sinks) over a network with capacity constraints in a collective fidelity metric over…
Joint Network-Source Coding: An Achievable Region with Diversity Routing
Nima Sarshar, Xiaolin Wu
We are interested in how to best communicate a (usually real valued) source to a number of destinations (sinks) over a network with capacity constraints in a collective fidelity me…
Disaster Management in Scale-Free Networks: Recovery from and Protection Against Intentional Attacks
Behnam A. Rezaei, Nima Sarshar, P. Oscar Boykin +1
Susceptibility of scale free Power Law (PL) networks to attacks has been traditionally studied in the context of what may be termed as {\em instantaneous attacks}, where a randomly…
