Study on improvement of Performance of Call of IP PBX embeded using the Cashing Method

Ubiquitous environments make it possible to connect people and objects together seamlessly using networking technology. To realize ubiquitous environments many kinds of devices should follow the exact protocol. To observe protocol and prepare the increasing network traffic are very difficult in the aspects of maintenance, so the new efficient technology is required. Wimedia technology is a prominent ubiquitous technology which can make connection with many devices. This paper propose a energy efficient method for Wimedia bridge implementation which is a part of scale-free uPAN systems. The proposed method can reduce network expenses which is generated by protocol requirements by adding efficient packet encapsulation and bridging technology. It can be proved to be more time and energy efficient by simulations.
