Mobile Computing Functions

We can define a computing environment as mobile if it supports one or more of the fol­lowing characteristics:

·   User Mobility: User should be able to move from one physical location to another location and use the same service. The service could be in the home net­work or a remote network. Example could be a user moves from London to New York and uses Internet to access the corporate application the same way the user uses in the home office.

·   Network Mobility: User should be able to move from one network to another network and use the same service. Example could be a user moves from Hong Kong to New Delhi and uses the same GSM phone to access the corporate appli­cation through WAP (Wireless Application Protocol). In home network he uses this service over GPRS (General Packet Radio Service) whereas in Delhi he accesses it over the GSM network.
