This abstract propose a distributed overlay protocol, called SkipCloud, to organize servers in the cloud computing environment. SkipCloud enables subscriptions and events to be forwarded among brokers in a scalable and reliable manner. Also it is easy to implement and maintain. To achieve scalable and reliable event matching among multiple servers, we propose a hybrid […]
A Homomorphic Linear Authenticator (HLA) Based Public Auditing Architecture For Verify The Truthfulness Of The Packet Loss Information In Wireless Ad Hoc Networks
In a multihop wireless network, nodes cooperate in relaying/routing traffic. An adversary can exploit this cooperative nature to launch attacks. In this abstract, while observing a sequence of packet losses in the network, we are interested in determining whether the losses are caused by link errors only, or by the combined effect of link errors […]
A Scalable And Reliable Event Matching Service For Content-Based Pub/Sub Systems In Cloud Computing Environment
In this abstract, we propose SREM, a scalable and reliable event matching service for content-based pub/sub systems in cloud computing environment. To achieve low routing latency and reliable links among servers, we propose a distributed overlay SkipCloud to organize servers of SREM. Through a hybrid space partitioning technique HPartition, large-scale skewed subscriptions are mapped into […]
A Novel Approach Based On The Partially-Supervised Alignment Model For Mining Opinion Targets And Opinion Words From Online Reviews
To extract and analyze opinions from online reviews, it is unsatisfactory to merely obtain the overall sentiment about a product. In most cases, customers expect to find fine-grained sentiments about an aspect or feature of a product that is reviewed. To this end, this abstract proposes a novel approach based on the partially-supervised alignment model, […]
