Supervisor Meeting 10 Nov 2009 (O’Sheas)

November 10th, 2009 No comments

Had a meeting with Paddy in O’Sheas.
The main outcome was that I need to come up with some refined research questions, in the next two and a half weeks, that really define what I will do for my PhD, they should be structured in a way that must really get to the point about what people have done so far, what we will do, and how we think this will make some difference. It must be clear what our work compares to and what metrics it can be measured agains. At the lower level, we have to show how these questions lead us to the experiments we want to perform, and how these experiments will help us prove our point. At the highest level, we need to step back and look at the big picture, and see what it is that our work contributes to .

Practically, I will start a google wave as part of the workup of these ideas, which I will share with Paddy, the protocol being that when one of us makes a change, we will email the other.

When Paddy is back, we will get together to go over what we have come up with, and then later in the week I will present a few pages of my ideas to GW, DC and others, to get their input on the direction of the research.

Paddy also said that funding wise, his plan is as follows: He will guarantee that fees will be paid when IRCSET runs out, and if I cannot get an extension, he will make sure that I can get funding from somewhere if he can. The overall plan being that I have another 14 months of funding, meaning that I should spend the next 8 months working on PhD experiments and ideas etc. Then the final 6 months writing up.

Paddy also asked if I wanted to become a part of Clarity,  in the sense that I would get access to their data, and they would be able to tick a box for extra people in Clarity seperately funded by IRCSET.  I did not make a decision, but it sounded like a good idea.

Paddy also asked if I would cover a lecture this week on P2P for Distributed Systems, and when I asked if I would get Leturers pay for it, he said he couldn’t pay me, but he would buy a small piece of technology for me.

I also asked about the possibility of getting  a new laptop, and he said that should be ok, and I spec one up that is not too expensive, but is still future proof . (IBM-Lenovo/Dell/Apple/)

As a suggestion towards good time management, Paddy suggested I make sure I am working on PhD stuff 4 days a week, and spend only 1 day working on related projects.

Discussion with Graham W

October 26th, 2009 No comments

Had a discussion with GW about other things to test within datasets, for example, what use is it to simulate message passing between users who do not know each other, and if we had some knowledge about this data, can we find a more efficient way to route messages. This led us to talk about:

  • how many nodes can you get to within x hops in a network?
    • how many paths between friends need to use strangers and vice versa – can be used rto define privacy rules too 🙂
    • see miklas paper about defining friends and strangers
    • The point being that you may never need to send a message to any body else

Graham showed me how to run the simulator he wrote, and we talked about writing a paper together for an upcoming conference – but decided the deadline was too soon, and that we didn’t have any new results to put into it.

Meeting – Basadaeir paper for IJHCR

September 7th, 2009 No comments

Met with Graeme, Paddy and Simon regarding a request for a submission to the IJHCR journal – from the pervasive LBR – Basadaeir paper

http://www.igi-global.com/ijhcr

We decided that even though its not directly related my research, it would be worth submitting, as we would all benefit from a journal publication, and this seems to be fairly low bar….

My job is to manage this project, and let paddy/simon/graeme know what they need to do – Paddy said he might even write something.

Graeme and I went through the basic structure of the project, and came up with some initial ideas.

The project will have to be re-worked quite substantially, and might need to be coded from scratch. I have some concerns about whether this is worth doing if it’s not going to be part of my research. Will discuss with Paddy tomorrow.

ODCSSS Meeting 18 June AM

June 18th, 2009 No comments

JP MS

We talked about where we are going with the project,I suggested 5 actions:

JP:

  • Write a project overview about his view on the project, print it out and keep it handy.
  • Write a pseudocode algorithm about how to implement routing protocol
  • Evaluate network simulators – NS2 & NS3

MS:

  • Send papers to JP – Spray and Wait, Bubble RAP, Traffic Gossip
  • Arrange Meeting with Olga/Neil

Both

  • Arrange meeting with paddy

JP wants to work with the actual implementation, rather than just simulation, which is what I would choose too.

ODCSSS 2009

June 16th, 2009 No comments

I have taken on mentorship of an ODCSSS project which we have dubbed – CitySense. My student, John Paul Meaney, is currently working on plugging in movement models to TOSSIM and Tiny OS – and also implementing simple DTN protocols. We have chosen TinyOS and TOSSIM so that we are able to easily test this in the real world, to compare data with simulation data.

Mini-Project discussion with Davide

April 9th, 2009 No comments

Met with Davide at the whiteboard on the 3rd floor lobby to discuss and mini-project for me to do.

Meeting with Davide 09th Apr 2009

In the context of mobile sensor nodes, he would like to discover if we can reduce the overall total of Neighbors nodes (i.e. the sum over all nodes, of the number of neigbors each node has)

E = SUM(0 to n: total neigbors)

Construct a lattice of size L2 with N nodes, Each node may only move along the lines of the lattice, each costing 1.

Time is discreet, at intervals 1,2,3 … n etc. and

at each time step,

a node at random is picked,

if the node has less than or equal to C neighbors, then it picks one of the four surrounding points, and if that point is empty, it moves to that point, else it stays where it is.

else if the node has a value greater than C neighbours, it will pick a a diagonal position (2 hops) at random, and if it is not occupied, it will move, else it will stay where it is.

(Nodes will not bounce off the side of the lattice, but will continue to the other side.)

We will measure the value of E over T (time), and also the cost of movements.

T is not the timesteps, but each discreet value of T is the next step when each node has on average had the chance to move once (i.e. T is when t equals the number of nodes)

The overall effect should be to reduce density, speedily, as when there are too many neighbors, movement is ‘faster’ i.e. more hops.

The idea is to simulate this to generate some nice graphs

Passed Paddy and Simon in corridor! 02 Dec 2008

December 2nd, 2008 No comments

Also, met Paddy and Simon in the corridor and asked them to take a look at my idea for my PhD Transfer Symposium Talk, they seemed to think it’s a workable idea, and I need to work it up into a presentation.

I mentioned that I would have liked to have read more around the subject, and I will do, but Paddy said that its more important that I show what I have read, for example, alot about context aware systems, that fits into this idea – as it is context-aware routing.

Also showed paddy my ideas for short term research projects, and he thinks the WaveLAN one might be interesting.

Construct Seminar 02 Dec 2008

December 2nd, 2008 No comments

This mornning was the construct seminar in CASL, where bashed out some ideas about the future of construct:

The speakers were:

Graham Stevenson, Graham Williamson, Stephen Knox, Adrian Clear, Matt Stabeler (presentation), Suki, Donal Simmie, Erica (Juan Ye), Susan McKeever and Simon Dobson. Others present were Paddy Nixon, Ross Shannon, Wei Zhou, Lorcan Coyle among others….

We talked about a number of things, and whilst we didn’t have conclusions, we came up with some thing to think about:

  • Mobile / Lighweight
  • Multiple Distribution protocols / modules
  • Multiple inferencing modules
  • Justification for te RDF models we use
  • Construct Need and end goal
  • It needs an Application Showcase to show off to potential users / developers

Meeting with Fred Clarke and John Curran 26th November 2008

November 26th, 2008 No comments

Met with John Curran and Fred Clarke regarding using logs from the wireless access points

The data available for WaveLAN is building level DHCP leases, but not AP level information, this is available to us, as it is pretty much anonymous.

The data available from the Eduroam system is more detailed an includes authentication information, access point details etc. we would need to discuss how we would anonymise this data before we could use it.

Neil O’Reilly would be able to give use a sample of the logs for the wavelan network, so we could see what information is available,

We need to send a doc to give the following:

who has access
how long we will keep it
how we would dispose of the data
e.g. assume this is personal data, how will we deal with it?

Meeting with Paddy 20 Nov 2008

November 20th, 2008 No comments

Brief meeting with paddy.

We both like the idea of the City wide sensing idea using mobile devices. I mentioned that Jo K had thought the whole routing thing had been done, but paddy suggested that there is different view on similar problems that still yield interesting research topics.

We discussed simulations, and I mentioned the idea of using some datasets from Dublin traffic, and maybe even the wireless access point data from UCD campus to simulate social networks.

Paddy mentioned an IBM city simulator that has since disappeared, but will see if he can find out more about it (I will too).

Going forward, I should have a project to get my teeth into, that has some proper research outcomes, which should be a shot term project – 3 months.

I will arrange a meeting with myself, Paddy, Aaron and Simon for sometime very soon to come up with ideas.

I should probably come up with some suggestions to work with, for what the project could be. *thinking cap on*
