Here are some of the basic characteristics of mobile computing mentioned below:
- User Mobility
- User should be able to move from one physical location to another location and use the same service.
- Example: User moves from London to New York and uses the Internet in either place to access the corporate application.
- Network Mobility
- User should be able to move from one network to another network and use the same service.
- Example: User moves from Hong Kong to Singapore and uses the same GSM phone to access the corporate application.
- Bearer Mobility
- User should be able to move from one bearer to another while using the same service.
- Example: User is unable to access the WAP bearer due to some problem in the GSM network then he should be able to use voice or SMS bearer to access that same corporate application.
- Like Hike Messenger
- Device Mobility
- User should be able to move from one device to another and use the same service.
- Example: User is using a PC to do his work. During the day, while he is on the street he would like to use his mobile to access the corporate application.
- Session Mobility
- A user session should be able to move from one user – agent environment to another.
- Example: An unfinished session moving from a mobile device to a desktop computer is a good example.
- Service Mobility
- User should be able to move from one service to another.
- Example: User is writing a mail. Suddenly, he needs to refer to something else. In a PC, user simply opens another service and moves between them. User should be able to do the same in small wireless devices.
- Host Mobility
- User should be able to move while the device is a host computer.
- Example: The laptop computer of a user is a host for grid computing network. It is connected to a LAN port. Suddenly, the user realizes that he needs to leave for an offsite meeting. He disconnects from the LAN and should get connected to wireless LAN while his laptop being the host for grid computing network.
