- Mobile nodes, wireless links
- No infratsructure
Done by the nodes themselves
- Multi-hop routing
Done by the node themselves
- minimum management

- A network in which the locations of the switches, hubs, or routers can be mobile
- Self-organizing;  No pre-existing infrastructure
- Routes between nodes may potentially contain multiple hops
- Nodes act as routers to forward packets for each other
- Node mobility may cause the routes change

- All packets carrying information must be authenticated.
- Avoid “remote redirection” attacks
- Allows MN to allow more than one care-of addresses at a time, but registers only one of its bindings.
- Allows CN to dynamically learn the MN’s binding.
- In this case it uses the Routing header but does not encapsulate.
- Reasonable to expect all the IPv6 nodes to have caching capabilities.
- Implementation of the Binding Updates and Binding Acknowledgments -the key to reliability and optimization. and optimization.
- Always uses Route Optimization to improve the routing performance by avoiding the triangle routing problem

• IPv6:

- 128 bit address space
- link local addresses

• Extension headers :

- Destination Options header,
- Destination Options header,
- Hop-by-hop header
- Routing header
- Authentication header.

• RFC 3220

• has many features we’ve seen:

- home agents, foreign agents, foreign-agent registration, care-of-addresses, encapsulation (packet-within-a-packet)

• three components to standard:

- indirect routing of datagrams
- agent discovery
- registration with home agent

• suppose mobile user moves to another network

- registers with new foreign agent

- new foreign agent registers with home agent

- home agent update care-of-address for mobile

- packets continue to be forwarded to mobile to be forwarded to mobile (but with new care-of-address)

• mobility, changing foreign networks

- transparent: on going connections can be maintained!

• Mobile uses two addresses:

- permanent address:used by correspondent (hence mobile location is transparentto correspondent)
- care-of-address:used by home agent to forward datagrams to mobile

• foreign agent functions may be done by mobile itself

• triangle routing:correspondent-home-network-mobile

- inefficient when correspondent, mobile are in same network

Let routing handle it: routers advertise permanent address of mobile-nodes-in-residence via usual routing table exchange.

- routing tables indicate where each mobile located

- no changes to end-systems

Let end-systems handle it:

- indirect routing:communication from correspondent to mobile goes through home agent, then forwarde to remote

- direct routing:correspondent gets foreign address of mobile, sends directly to mobile

Product Concepts

GPS Auto Silent is an application that can use your current location and depending on that set it to auto silent to even changing the type of ring tones (profile type). Similar to iPhone application that uses time setting to silence the mobile, our application is going to use the location base on GPS. Features of our application are changes sound settings automatically when user is in “do not disturb” GPS location. The application reverts back to original sound settings once general location. It flexibility to configure ring tone, calendar alert, SMS alert, new mail alert, and to configure dose not disturb location. Flexibility to configure does not disturb location. Application runs in background, no need to keep application open. Next is the application that related to GPS Auto Silent, and how it does relevant.

Lists of Inspirational Application

1. 1. iPhone Auto Silent (Time Setting)

The key feature of this application is similar to our application that need to silence automatically but different in the way to do which we use GPS location is stead of time setting.

1. 2. Google Maps for Mobile

Google Maps for Mobile helps to determine your current location with or without GPS to get driving and transit directions, addresses for local businesses, so we can use the location for setting to silence in our application by this.

1. 3. Localized Silence Area for Mobile Device

Localized Silence Area for Mobile Device is a method to create a localized silence area, allows mobile device registered with an access point base station which is similar to our application that change from access point to GPS location.

Deep Analysis of 3 Applications

1. 1. iPhone Auto Silent (Time Setting)

“Auto Silent” is application to disable or bypass iPhone Silent switch. If your switch was broken in silent mode, it will restore all sounds including ring. Then you can use Auto Silent app to put phone into silent mode. There is provision to put phone into silent mode automatically using pre-configured settings in the app or according to appointments in iPhone Calendar. There is Provision to put phone into silent mode based on timer. The phone will come out of silent mode automatically once timer goes off.  The key feature that we will use in our application is auto silent mode. The method to change the profile to silence mode may borrowed by us.

1. 2. Google Maps for Mobile

Google Maps for Mobile helps to determine your current location with or without GPS to get driving and transit directions, phone number and addresses for local businesses. Google Maps for mobile works on most phones, including those that run the below platforms. Some mobile phones also support the ability to side load Google Maps onto your phone. We can use the GPS location from Google Maps to setting in our application. The reason that we choose Google Maps instead of another GPS program because Google Maps can use the antenna changing for getting a location in the building or some place that unable to use GPS directly.

1. 3. Localized Silence Area for Mobile Device

Localized Silence Area for Mobile Device is a system and method for creating a localized silence area. A mobile device may be registered with an access point base station. Any direct communication links from the mobile device to any other base stations may be removed. An indication may be given to the mobile device that the mobile device is in a localized silence zone. The indication may include a request that the mobile device operate in a silent mode, information about making outgoing calls, information about receiving incoming calls, or a combination of these. Procedures for incoming voice calls to the mobile device may be different for different priority levels. The method to use direct communication link is similar in working with our application in changing antenna in the building. We can swap from mobile changing antenna to access point base station to cover the working in each room of building, for example meeting room.

1. Expert can use this simple model to estimate their confidence.

2.  Belief and disbelief can be expressed for  each hypothesis.

3.  Quantification of uncertainty can be incorporated into the rules.

4.  Simplify methed.

Disadvantages

1. Nonindependent evidence must be expressed in the same rule.

2.  CF values are unable to  represent some certain dependencies between uncertain beliefs.

3.  Adding new knowledge of the hypothesis and the evidence would stir the existing system.
