We are working with Dr Zaidi the new head of SEECS to investigate resources need to continue support of PingER in Pakistan. We communicated first week in August. No word since. Sent a reminder 8/1/2015. We had a rump meeting of Anjum, Hassaan and Les to discuss the way forward.
- NETAPPS2015: Adib reports "We have received some good number of submissions and the reviewing process have started already. we will have a committee meeting tomorrow at the same time of PINGER group meeting. I will update you afterward."
Four papers were submitted related to PingER August 25th
Anjum submitted a paper to NETAPPS2015 "Adaptive Geolocation of Internet Hosts"
Les, Thiago, Johari, Bebo and Topher White submitted a paper on "Worldwide Internet Performance Measurements Using Lightweight Measurement Platforms"
Saqib submitted a paper "PingER Malaysia-Internet Performance Measuring Project: A Case Study". This paper needs reformatting, Saqib is working on it. It also needs reviewing. Les will look at.
Thiago and the Brazilian team submitted a paper on "Applying Data Warehousing and Big Data Techniques to Analyze Internet Performance'. Adib has kindly come up with a way in which the authors are unlikely to be able to attend, so somebody else will present. This has been accepted
Bebo has potentially 9 students from India interested in coming to SLAC for 3 months starting Feb. We are looing looking at what they can be involved in. Possibly 2 on PingER, Android, others on big data, monitoring etc.

Anjum believes the TULIP Geolocation application can be improved significantly. At least there are few ideas that we can try. For this, either a group of undergraduate students or an active masters student is required. The resultant work can easily be the thesis of masters level. Who is interested?
Saqib is going to see if he has a student interested. He will contact Anjum to learn more. Update Saqib, Anjum not heard
Johari will contact Anjum to learn more of the requirements. Update Johari/Adnan
See http://www.slac.stanford.edu/comp/net/tulip/. Basically TULIP uses pings to a target from landmarks at known locations and converts the minimum RTTs to estimate the distances. Then uses the distances with mulitlateration to estimate the location of the target
To improve TULIP one needs the right selection of landmarks, i.e. good (working landmarks) at the right locations (not too far from the target), straddling the target, and with a a reasonable estimate of the indirectness (directivity or alpha) of the path from the landmark to the target (so we can reasonably accurately estimate the distance). One also needs a reasonable density of landmarks (e.g. number of targets/100,000sq km)
The landmarks come from PingER and perfSONAR sites. We have a reasonable density in the US, Pakistan and Europe. Currently Anjum is getting better than 20km accuracy for Pakistani targets
As the number of landmarks goes up so does the accuracy, but so does the time to make the measurements (pings).
One needs to find the optimal density
Anjum proposes to speed up the measurements using a cluster for parallelization and also proposes to improve the adaptation of alpha based region. He regards the adaptive geolocation and parallelization as MS projects
He is also interested in geolocation in small proximity (e.g.indoors), e.g. using cell tower signals. This is a new area of research. It is possible that the port of PingER to an Android could be rleated to this. This is a PhD project
