Abstract: At present, the VoIP is a fashion application of Internet. However,
because they cannot communicate each other among various protocols of VoIP,
it is necessary to install the VoIP-application for that specific group if
these users having different VoIP protocols wish to communicate. For
interworking between different VoIP groups, the two major players of the
instant message, Yahoo Messenger and MSN Messenger, have provided an
integration project. Thus, the interworking of the heterogeneous-VoIP has
become a trend. Besides, the VoIP users can be classified into two groups,
SIP and Skype. Therefore, to communicate both groups of users, SIP and Skype,
a connection system of the heterogeneous-VoIP with a man-in-the-middle
mechanism is provided and practiced in this study.

Abstract: In recent years, people are more reliant on wireless network services in order to obtain latest
information at anytime, anywhere. For wireless networks, the allowance of several mobile devices to send data
among one another effectively has become an important research topic. In this paper, a mechanism for the
designation of clustering and cluster manager is given by mobile Ad-hoc network. The proposed mechanism
adopts the center manager to improve the stability of network topology, assists Mobile Host within the working
area, and takes advantage of message exchange. Keywords:
Mobile ad-hoc network, Center-based, Hierarchical manage, Manager selection
