Abstract
Cloud computing has been the most prevalent technology in the past few years and many prominent enterprises have prompted their cloud systems, preparing for the coming age of cloud computing. We can predict that the mobile area will take on a boom with the advent of this new concept. While due to the inherent characteristics of mobile environment, challenges like mobility, heterogeneity and low band-width will hinder the advancement of this incorporation. In this paper we will introduce a ne ....etc

Abstract
A new mobile computing model of spatial information service is studied based on grid computing environment. Key technologies are presented in the model, including mobile agent (MA) mobile computing, grid computing, location based service (LBS) ,global positioning system (GPS), and wireless communication technologies, such as, general packet radio service (GPRS), transfer control protocol/internet protocol (TCP/IP), and user datagram protocol (UDP). In order to deal with the narrow bandwidth and instability of the wireless inter ....etc

Abstract
Cloud computing provides people the way to sharedistributed resources and services that belong to differentorganizations or sites. Since cloud computing share distributedresources via the network in the open environment, thus itmakes security problems important for us to develop the cloudcomputing application. In this paper, we pay attention to thesecurity requirements in cloud computing environment. Weproposed a method to build a trusted computing environmentfor cloud computing system by integrating the trustedcomputing platf ....etc
