Abstract
The focus of this chapter is on techniques for providing system-level support for mobile operation. In particular, we discuss support for:
-
■Disconnections: Wireless computers are only intermittently connected to a network. Thus, support for disconnected operation — autonomous operation of a mobile host during disconnection — is crucial.
-
â– Weak connectivity: Operation should be tuned for communication environments characterized by low bandwidth, high latency, and expensive prices.
-
â– Mobility: Support for mobility may be as simple as establishing new communication links or as complicated as migrating executing processes and database transactions in progress.
-
â– Failure recovery: Since mobile elements are prone to hard failures, methods for failure handling and recovery are important.
