1. An on-line retailer has recently bought a dozen Segways (personal motorised scooter-like devices) to help their staff move quickly about the warehouse when picking and packing items for each order. They want to track the Segways within the warehouse (e.g. to help optimise their use) and also warn the driver of imminent collisions with other Segways. Describe an RFID-based scheme for sensing the location of the Segways to within about 3 metres using no more than one RFID reader per Segway. The RFID readers have a range of about 50 cm. Your description should include:

(a) A clearly drawn diagram showing how each component of the technology is positioned or attached;
(b) How each component is used including the flow of information through the system to a central database and web-interface;
(c) The database table layout (showing keyed fields) and some example rows (hint: think about how to keep track of past history also);
(d) A diagram showing the web-interface including any buttons and an example of how the location of several Segways are identified;
(e) An explanation of how the collision detection should work. Include any assumptions made and / or changes to the database structure. In particular, explain how the direction of movement is established;
(f) A description of what happens (in database terms) when the same tag is read by the same tag reader twice or more in rapid succession. Why might such a thing occur?

2. Environmental monitoring has been made possible by advances in pervasive computing.
a) Name 3 types of environmental sensors and provide, for each of them:
(i) A usage scenario where and why this sensing would be important.
(ii) Specification for deployment density (number of sensors to be deployed in that scenario).
(iii) A typical example of sensor values and decisions that could be made based on the data

b) Describe an environmental monitoring application based on embedded networked sensing, presenting:
(i) The overall aim of the application, including the stakeholders
(ii) The equipment used, including a block diagram of the end-to-end system
(iii) A critique of the application in terms of its likely commercial success
