Does Multi-hop Communication Enhance Localization Accuracy?
A new work, co-authored with Walid Ibrahim and Hosssam Hassanein, has been accepted in Globecom’13 taking place in Atlanta during December 9-13, 2013.
Abstract -Â Estimating the location of sensor nodes in wireless sensor networks is a fundamental problem, as sensor node locations play a critical role in a variety of applications. In many cases the area covered is very large so that it is impossible to localize all sensor nodes using single-hop localization techniques. A solution to this problem is to use a multi-hop localization technique to estimate sensor node positions. Multi-hop localization techniques are classified into two categories: range-based and range-free. Despite the numerous existing localization techniques, the fundamental behavior of multi-hop localization is yet to be fully examined. The aim of this paper is to study the effect of errors in a multi-hop localization environment and how it impacts localization accuracy. There has been a general belief that a fewer number of hops results in higher accuracy. Through different experiments on two generic localization techniques representing both categories of localization schemes, we show that this belief is not true in all cases, as in dense environments using shorter hops gives better accuracy.
Remote Wellbeing Monitoring in 4G Networks
A proposal for a tutorial at the IEEE ICC’12 was accepted!
The tutorial will talk about “Remote Wellbeing Monitoring in 4G Networks”, and will be presented by Najah Abu Ali, Hossam Hassanein and myself.
Further details to follow.
Networking Life
Some time earlier this year I was asked to be a panelist in the second Queen’s Graduate Computing Society Conference. At the time, I thought it would be a good idea to expose the students that there’s more to networks than streams of data and routers.
More recently, I had a chance to revisit the topic. With more time to present than before, I thought I’d give the talk more depth.
My inspiration for the talk came from two books that offered a general view of Networks. One by M. E. J. Newman called “Networks: An Introduction“, the other by David Easley and Jon Kleinberg called “Networks, Crowds, and Markets: Reasoning About a Highly Connected World“.
You can find my slides here. Also, a “write up” version ought to be coming up soon.
