RESEARCH ARTICLE OPEN ACCESS Study of Server Scalability Issues in Mobile Presence Services

With the development of wireless telecommunication technologies, many customer services that are used in the computer-based Internet have also appeared in mobile phones. Mobile instant message (MIM) is a typical example..MIM enables consumers, whether sitting at the computer or on the road, to connect instant message (IM) with existing communities and social services.

Because it maintains each mobile user’s presence information, such as the current status (online/offline), GPS location and network address, and also updates the user’s online friends with the information continually. This presence update occur frequently so enormous messages are distributed by presence server may lead to a scalability problem in a large-scale mobile presence service. This paper gives a survey of presence services of existing and proposed systems and their server scalability issues. Various Instant Messaging services (IM), VoIP services are discussed here..Keywords:- Social networks, mobile presence services, Instant messaging. I
