In this project, two tasks are to be completed:
(a) Examine the existing message structure
of OCO and, if possible, define a simplified message structure.
(b) Devise a simple authentication,
similar to the authentication method proposed in the TinySec protocol,
and add it into the OCO method.
For task (a):
In this working paper “OCO: An Efficient Method for Tracking
Objects in Wireless Sensor Networks”, the current message
structure of OCO are summarized as 14 types of messages (in Tables 1, 8, 9,
and 10). Examine the messages and propose a simpler structure to represent
the messages (for example, by combining several message types into one). Explain
why your new message structure will provide the same functionalities as the
old structure.
For task (b):
Devise a simple authentication mechanism, similar to the
authentication method proposed in the TinySec
protocol, and add it into the OCO method. The added authentication should
allow the messages transmitted between two entities (for example,
border-to-forwarding, forwarding-to-forwarding, forwarding-to-base) to be
authenticated, meaning the recipient of a given message will be able to
authenticate the message, before deciding whether to accept and process the
incoming message or not. Complete the following two sub-tasks:
(b.1) Show how authentication may be added to the 14
message types.
(b.2) For the sake of testing the authentication methods,
implement your authentications for message types 8 and 9 (M8: Message from a node to the base to report intruding
objects; M9: Message from an active
node to nearby forwarding nodes to
activate their sensor modules) in OCO. Prepare at least two cases
where the authentication between two entities would fail and succeed,
respectively. Show a demo in the class (or to the instructor).
- The revised message
structure.
- The message
structure with authentication added.
- Revised OCO source
codes with the authentications incorporated.
- A demonstration of the
revised OCO program.

Final report
Note: This is an individual project.
Items to be submitted:
- The abstract
A preliminary abstract of your
presentation topic is due early in the semester.
Each student should submit to the instructor an abstract
(via email to yang@uhcl.edu).
The abstract should be 2-3 pages long (single spacing,
12-point font), and contains the following sections:
(1)
Class name (i.e., CSCI5234 Web Security)
(2)
Your name and an email address that you check
regularly (that is, at least once a day)
(3)
Topic of your investigation
(4)
General description of the topic
(5)
Why is the topic worth investigating? How is it related to wireless
sensor networks?
(6)
Three or more articles related to the topic.
VERY Important: Make
sure you properly cite the work of other researchers or professionals. Visit http://sce.uhcl.edu/yang/citing.htm
for more information about cited references.
Warning: Missing
or improper cited references in your abstract and final report will result in
poor score for your presentation.
(7)
A tentative outline (agenda) of your final
report, that is, the content you plan to include in the final report.
- The final report
- The written report should include your findings
about the chosen topic.
- The report should be submitted to the instructor
(yang@uhcl.edu) via email.
It should have 10-15 pages (single spacing, 12-point
font) with proper cited references.
Warning: Missing
or improper cited references in your abstract and final report will result in
poor score for this assignment.
- The report should be composed of the following
sections:
i.
Title
ii.
Your name (and email address)
iii.
An abstract (50-100 words)
iv.
Introduction to the topic
v.
