A Survey on Presence Cloud based solution for on demand data in wireless computing devices

Abstract

The main objective of this paper is to propose an on demand QoS routing algorithm. Since the requirements for various applications may vary time to time, the approach for QoS routing may not be proactive. The proposed approach has two phases namely route discovery phase and route maintenance phase. When a source node has to pass data to a destination node with QoS requirements it starts with the route discovery phase. Once the route is found, the data transfer will take place. While data transmission is going on, it is also required to maintain the path to the destination. This is very much desirable and required in mobile ad hoc networks and hence is done in the route maintenance phase.
