Adopting Cloud Computing Technique for Efficient Event Forwarding Service To Users

Forwarding large volume of live content to relevant users in scalable efficient way in emergency application is main challenging task. One of the model named as the publisher and subscribe is used to forward the event service to users. but it fails to provide relevant event match services to subscribers another major problem is server fail .To handle this problem adopting cloud computing which provides complex computing and reliable communication. In this project proposing distributed overlay SkipCloud  to organize servers giving efficient scalable and reliable event matching services to subscribers. To partition the similar subscriptions in same server for each event hybrid multi-dimensional space partition technique is used. Finally proposed techniques shows efficiency in high matching event service and reduces the event forwarding delay

Towards a fully mobile publish/subscribe system

93 p.This PhD thesis makes contributions to support mobility and fault tolerance in a publish/subscribe system. Two protocols are proposed in order to support mobility of all devices in the system, including inside the event notification service. The protocols are designed with the idea that any change due to mobility is completely beyond our control and ability to predict. Moreover, the proposed solutions do not need to know neither the amount of nodes in the system nor their identities before starting, the system is able to adapt to new devices or disconnections and is able to keep operating correctly in a partitioned network. To do so we extend a previously proposed framework called Phoenix that already supported client mobility. Both protocols use a leader election mechanism to create a communication tree in a highly dynamic environment, and use a characteristic of that algorithm to detect topology changes and migrate nodes accordingly
