Global Positioning System (GPS) is becoming widely used for tracking and monitoring vehicles. Many systems have been created to provide such services which make them popular and needed more than ever before. In this paper a “GPS vehicle tracking system” is proposed. This system is useful for fleet operators in monitoring driving behavior of employees or parents monitoring their teen drivers. Moreover,...
Aiming at the problems of implementing the conventional IKE authentications such as pre-shared key and certificate-based Public Key Infrastructure (PKI), this paper proposes a new certificateless IKE authentication scheme. This scheme uses bilinear pairing to structure the framework of certificateless IKE authentication, solves the end to end IPSec security by removing the requirement of both nodes...
The presence of IPv4/IPv6 translation gateway provides transparent routing mechanism to IPv4-only nodes and IPv6-only nodes which trying to establish communication from disparate address realms. However, the mechanism breaks TCP/IP intrinsic functionalities that results in IPSec cannot be applied in this environment. The existing solutions to address the compatibility issues between translation gateway...
Formulation of efficient algorithms to check implication and satisfibality for relational queries is an important research issue. Implication and satisfibality checking can be used to find query containment in semantic cache query processing and other similar applications. Description logic (DL) is a formalism used to model knowledge of a domain in the form of concepts and a rich set of associations...
Data access latency can be reduced for databases by using caching. Semantic caching enhances the performance of normal caching by locally answering the partially overlapped queries. Query processing (generation of probe and remainder query from the incoming queries) and cache management need to be addressed in its totality to really enjoy these benefits. That is, there is a need of correct, complete...
The importance of the cache is very apparent in the field of computer science. The semantic cache increases its significance by attaching additional meaningful information with the queried data in the cache. XML is used to provide the structure for the data available on the Web. Therefore it is widely used in many organizations for transmitting the data. The structure of XML data files is different...
