In the private index predicate encryption scheme, the ciphertext not only hides the message, but also hides the attributes. Predicate encryption scheme can enforce the fine grained access control over the encrypted data and perform selective search on the encrypted data. However, the main efficiency drawback of predicate encryption scheme is that the size of the ciphertext and the time required...

Cloud gaming is a relatively new paradigm in which the game is rendered in the cloud and is streamed to an enduser device through a thin client. Latency is a key challenge for cloud gaming. In order to optimize the end-to-end latency, it is first necessary to understand how the end-to-end latency builds up from the mobile device to the cloud gaming server. In this paper we dissect the delays oc...

The number of mobile phone subscribers is reaching 5 billion. Mobile phones are increasingly used for collaborative applications, such as IM, Facebook, and those for traffic and environmental sensing. As these applications are becoming pervasive and large-scale, much is left to be desired in terms of energy efficiency. These applications are collaborative and must share information among the pa...

The concept of multi-access edge computing (MEC) has been recently introduced to supplement cloud computing by deploying MEC servers to the network edge so as to reduce the network delay and alleviate the load on cloud data centers. However, compared to a resourceful cloud, an MEC server has limited resources. When each MEC server operates independently, it cannot handle all of the computationa...

This code contribution paper provides an overview of the RSPSIM model, which is a simulation model for the Reliable Server Pooling (RSerPool) framework. RSerPool denotes an IETF standard for the management of server pools and sessions with these pools. Such mechanisms are also crucial in the context of cloud computing research.

Cloud is an on demand service provisioning techniques uses virtualization as the underlying technology for managing and improving the utilization of data and computing center resources by server consolidation. Even though virtualization is a software technology, it has the effect of making hardware more important for high consolidation ratio. Performance and energy efficiency is one of the most...

Cloud Computing offers dynamic allocation of resources for guaranteed and reliable services. Users store their data on a single virtual server, when user wants to access any data that data might be changed or modified by unauthorized people for malicious purpose because user’s do not have direct control of data So security is a big challenge for cloud computing and it is necessary to increase t...
