This paper presents a fast selective look-ahead map-matching technique, called SLAMM. Existing MM algorithms developed for real-time location tracking of a moving vehicle are ill-suited for matching large collections of war-driving data due to the time complexity. Another unique feature of SLAMM is the map-matching of critical location samples in an AP trace to the road network before matching non-critical samples. Our experiments over a real dataset of 70 million AP samples show that SLAMM is… Show more

Another unique feature of SLAMM is the map-matching of critical location samples in an AP trace to the road network before matching non-critical samples. Our experiments over a real dataset of 70 million AP samples show that SLAMM is accurate and significantly faster than the traditional MM approaches. Show less

A study of the post-conflict ICT infrastructure and diffusion in Liberia.

This paper presents a location estimation method that improves location accuracy for WPS through the use of digital map-matching of wardriving data. We have conducted initial experiments to evaluate our map-matching algorithm along with the enhanced location estimation approach and demonstrate its effectiveness for measuring and improving the accuracy of large-scale wireless positioning systems. We demonstrate extensions to a look-ahead map-matching algorithm to improve the accuracy and… Show more

While the notion of hyperlink databases has been around since the beginnings of hypertext, the Web provides the opportunity to experiment with the largest open distributed hypertext system. The addition of hyperlink databases to the Web infrastructure positively impacts several areas including: referential integrity, link maintenance, navigation and visualization. This paper presents an architecture and migration path for the deployment of a scalable hyperlink database server called Atlas… Show more

While the notion of hyperlink databases has been around since the beginnings of hypertext, the Web provides the opportunity to experiment with the largest open distributed hypertext system. The addition of hyperlink databases to the Web infrastructure positively impacts several areas including: referential integrity, link maintenance, navigation and visualization. This paper presents an architecture and migration path for the deployment of a scalable hyperlink database server called Atlas. Atlas is designed to be scalable, autonomous, and weakly consistent.

This paper presents an environment for publishing information on the World-Wide Web (WWW). Previous work has pointed out that the explosive growth of the WWW is in part due to the ease with which information can be made available to Web users [23]. Yet this property can have negative impacts on the ability to find appropriate information as well as on the integrity of the information published. We present a prototype environment that facilitates the publishing of documents on the Web by… Show more

This paper presents an environment for publishing information on the World-Wide Web (WWW). Previous work has pointed out that the explosive growth of the WWW is in part due to the ease with which information can be made available to Web users [23]. Yet this property can have negative impacts on the ability to find appropriate information as well as on the integrity of the information published. We present a prototype environment that facilitates the publishing of documents on the Web by automatically generating meta-information about the document, communicating this to a local scalable architecture, e.g. WHOIS + +, verifying the document's HTML compliance, maintaining referential integrity within the local database, and placing the document in a Web accessible area. Additionally, maintenance and versioning facilities are provided. This paper first discusses an idealized publishing environment, then describes our implementation, followed by a discussion of salient issues and future research areas. Show less
