Solved: Project- Using Agile Techniques to Design A personal Environment Network


Using Agile Techniques, the students will design a Personal Environment Network. This will involve each student identifying and classifying which components need addressing and how, using Agile development, this will be achieved. The final outcomes of this will a document or documents addressing these components, (Communication, planning, modeling, construction and deployment).

Fundamental components to deliver in the project – Report will have these 6 sections:

1. Project planning

2. Use case development (a) Item identification and location

b) ad-hoc social networking

c) ad-hoc phone services (vs. cellular phone service))

3. Requirement gathering (requirements documentation)

4. Rapid design (design documentation/data flow design)

5. Code generation (no coding needed) can have objects and method explained

6. Testing (testing scenarios)

The user of the device sets their device to accept information from:

• Friends

• Ads by category

• Classmates (for example course 680)

• Device specifications in stores

• Home appliance devices


What I will give you here are some of the parameters for the PEN From these descriptions you need to create your requirements, unit test/use cases, prototypes (if needed) and a design doc for submission on the project These are the basic rules no internet no cell towers the device creates it's own network dynamically and is capable of mobility unlimited memory unlimited battery power no servers basically no fixed network to like to transceivers are embedded in almost all device, roads, table, chairs, product, building and so on, these device transmit according to their definition, for example, products in a store would transmit there relevant information, (without the use of a database)

The device is environmentally aware, in other words, it maps and displays according to environment by reading the sensors in the area, basically what you see as your environment is what the device can see (or more), so a classroom is an environment, a house is an environment, school is an environment, a store is an environment, these devices automatically create a network about the environment that they are in. There are three examples to focus on: Classroom or conference: In this case your device would automatically map out all the individuals of the room, faces and perhaps bio, and so on. Cell phones: The cell phones would route message thru the other phones eventually connecting to the receiver Stores:

The devices, upon entering a store, would map out the environment and detail all your like. One other thing, these devices learn, and one device is used probably for your entire lifetime, so as the device (lives) with you it learns your likes and dislikes (basically gets smarter), so when you go to stores, the device basically knows what you normally look for and what interests you. The deliverables are a requirements doc, functional spec (which links the requirements to the design doc), and a design doc, what you should have is enough documentation to give to a software company to produce a deliverable product that matches your requirements and design doc.

A personal Environment Network is a network of ad-hoc device (cell phones or other WIFI wireless devices) that organize themselves into an active network to exchange information that is determined by each individual device. The application that allows the information exchange is responsible for security, look and feel and protocol. The underlining communication protocol is also part of the application. Furthermore, the application is capable of routing thru a node to get a link to a node outside an original node transmission range. These devices do not need any cell tower requirements, although it is possible.

According to Wikipedia these devices follow this definition:

A mobile ad hoc network (MANET), is a self-configuring infrastructure-less network of mobile devices connected by wireless links. ad hoc is Latin and means "for this purpose". Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. Each must forward traffic unrelated to its own use, and therefore be a router. The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic. Such networks may operate by themselves or may be connected to the larger Internet. MANETs are a kind of wireless ad hoc networks that usually has a routable networking environment on top of a Link Layer ad hoc network.

The growth of laptops and 802.11/Wi-Fi wireless networking have made MANETs a popular research topic since the mid-1990s. Many academics papers evaluate protocols and their abilities, assuming varying degrees of Mobility within a bounded space, usually with all nodes within a few hops of each other. Different protocols are then evaluated based on measure such as the packet drop rate, the overhead introduced by the routing protocol, end-to-end packet delays, network throughput etc.

Beacons transmit data.  Personal Environment Network (PEN) does not need cell tower. No internet or intranet. Network is created from phone and they become the network.  Phones as our router and it configure itself based on all the device around it.  Everything you do is in the cell phone devices. Sensor on everything and PEN is the connection.  No WI-FI.
