A Study and Understanding of Mobile Presence Service with Enhanced Scalability in Social Network Application

Mobile presence service is a vital component of a social network applications due to mobile user’s presence details such as global positioning system location, network address, and online/offline status are continuously apprise to user’s online buddies. If persistent updates occur about presence information and also when servers disperse expansive number of messages scalability problem arises in large scale mobile presence service. In this paper a presence cloud which is scalable server architecture is proposed which support large scale social network application where it searches for the presence of his/her buddies and reveals them about his/her arrival. The performance results in achievement of small constant search latency by using direct search algorithm and one hop caching approach.
