This paper proposes self-deploying approaches for sensor networks. The gravitational field (GF) and the radioactive decay (RD) are used to model the repulsion forces between sensor nodes. The Received Signal Strength (RSS) is transformed to the repulsion force for computing the next move distance and direction. The GF approach reduces the power consumption on communication overheads while the RD approach...
Information privacy is usually concerned with the confidentiality of personally identifiable information (PII), such as electronic medical records. Nowadays, Web services are used to support different applications which may contain PII, such as healthcare applications. Thus, the information access control mechanism for Web services must be embedded into privacy-enhancing technologies. Further as application...
