Vehicular ad hoc networks (VANETs) have many new characteristics unlike traditional network, such as centriclessness, mobility and multi-hop transmission, which invalidate conventional key managements. The fast development and successful application of trusted computing technology provide a potential solution to achieve effective authentication and trust evaluation. According to the VANETs with hierarchy...
Mobile technology and advances in databases have allowed users to access and manipulate data across multiple heterogeneous and autonomous data sources via wireless connection, namely mobile multidatabase system. Transaction management in this environment is non-trivial due to heterogeneity and autonomy of the participating data sources, frequent disconnections, and technological constraints of the...
The advances in mobile devices and wireless networking technologies enable users to access information from anywhere and at anytime. In a mobile computing environment, mobile users often search for information with certain location restrictions; such searches are referred to as location aware queries (LAQs). Typically, the query is submitted to a proxy server, which may or may not have the desired...
We propose software agent-based ldquoforward analysisrdquo for efficient information retrieval in a network of sensing devices. In our approach, processing is pushed to the data at the edge of the network via intelligent software agents rather than pulling data to a central facility for processing. The agents are deployed with a specific query and perform varying levels of analysis of the data, communicating...
Pervasive computing enables seamless integration of computing technology into everyday life to make up-to-date information and services proactively available to the users based on their needs and behaviors. We aim to develop a transaction management scheme as a pertinent component for such environment supported by either structured or ad hoc networks. We propose transactional agents for pervasive...
