In order to support connectivity requirements for today's pervasive devices,
the
present invention provides an asymmetric two-way request-response communication
protocol in which the end user or application is an active participant in the power
management scheme. No power is consumed until a user-initiated client request is
made. At that time, the client activates its transceiver and attempts to connect
to the server; if it succeeds, it requests information, receives its response,
and disconnects again, totally shutting down the transceiver. The server's transceiver
always stays in a listening mode and waits for a client request. The protocol does
not provide a direct method for the server to send unsolicited messages to the client.
