  1. Urban Sensing • Jonathan Yang • UCLA CS194 Fall 2007

  2. What Is Urban sensing • Utilize mobile devices such as cell phones to participate in sensor networks that gather, analyze, and share sensor data. • Create a network that enhances sensor data credibility and quality while maintaining a level of privacy that users may desire. • Depending on the application of the sensor, urban sensing can help in areas such as public health, urban planning, and many more.

  3. Project goal • To create a network service that can attest to the GPS position of a cell phone’s location. • A network access point is able to detect the location of a device based on the signal strength between the two. • This data would be sent to our network server for analysis and processing. Ultimately, it would be sent to a client server.

  4. Project challenges • Learning how networking and routing work. • Accessing network packet data at different nodes in the network. • Possibly having to write software running on our network servers to process sensor data. • Sending processed data from our servers to end-client.

  5. past approaches • Network attested data can be used for security purposes. There have already been different implementations implemented by network architecture to improve security. • However, our network architecture not only can be used for the sake of adding credibility to sensor data, but also can allow the client to collect and access the data for other purposes.

  6. Initial checkpoints • Understand the network structure • Understand how routing operates on the network • Begin monitoring traffic on the network • Perform background research on urban sensing

  7. quarter Goals • By the end the fall quarter: • Send sensor data from mobile devices through the access point and router to UCLA server. • Write software for the server so that the sensor data can be extracted from network packets.

  8. Quarter Goals • By the end of winter quarter: • Establish a method for our network servers to add relevant sensor information onto the network packet. • The packet is sent through the router finally to the client where the sensor data can be assessed and utilized for whatever purpose.
