Network Group First Meeting - Summer 2003

[Joseph Peters <peters@cs.sfu.ca>]

NETWORK MODELLING GROUP
-----------------------

Group Interests
---------------

The Network Modelling Group is interested in all aspects of networking with a
particular emphasis on modelling and performance evaluation.  Anyone interested
in this research area is welcome to participate.  Graduate students are
particularly welcome.  The group was formed in September 2001 and meets most
Fridays.


Meeting Time and Place
----------------------

Our group keeps growing and even ASB 9705 seems crowded for some meetings.
For the summer, I have booked ASB 9896 on Fridays starting at 13:30.  I was
unable to find a room for May 30, so we might have to skip that week, but
we have ASB 9896 for all of the other Fridays.  Note that ASB 9896 has a
permanently mounted data projector, so it is not necessary to borrow a
portable one.


Group e-mail List
-----------------

Our e-mail list (net-model@sfu.ca) has grown to 55 addresses.  If you know
anyone who would like to be added, or if you want to have your address removed
from the list, please let me know.

Thanks,
Joseph Peters

Title:    High level SDL specification of a layered communication architecture
          for position-based routing protocol in mobile ad hoc networks

Juice and cookies will be provided.

Abstract:

High level SDL specification of a layered communication architecture for 
position-based routing protocol in mobile ad hoc networks.

Specification and Description Language (SDL) is an international standard by
ITU.  It is a graphical and object-oriented language.  The routing protocol I
will present is divided into two sublayers, one for the location service and
one for position based routing between known locations.  These two sublayers
cooperatively form the network layer of a mobile ad hoc net-work. The location
service is based on a highly fault tolerant, self-scaling architecture called
hypercubic location service (HLS).  For the position based routing sublayer,
the Yao-graph is used, which contains approximate power minimal routing paths.
The objective we use advanced SDL modeling techniques is to show a full
graphical modeling of the protocol based on the purely theoretical model and
sharpen loosely defined system requirements into an architectural specification.
The model will be served as a formal basis for analyzing key system properties
by experimental validation.
