Power Saving in Mobile Handover Networks Using Simple Protocol Architecture
Instant Messaging (IM) is a form of communication over the Internet that offers an instantaneous transmission of text-based messages from sender to receiver. Mobile Instant Messaging (MIM) is the technology that allows instant messaging services to be accessed from a portable device, ranging from standard mobile phones. But in MIM frequency exchange of presence information causes massive power consumption to mobile devices. Such power consumption penalty can render persistent-instant messaging infeasible for battery-powered mobile devices. In this paper, the author tries to propose solution to mitigate the power consumption problem. The proposed solutions are implemented using SIMPLE protocol; it is one of the instant messaging protocols. It is the extension of SIP (Session Initiation Protocol) protocol.
