IR-Tree: An Efficient Index for Geographic Document Search



INTRODUCTION
THE World Wide Web (WWW) has become the most
popular and ubiquitous information media. According
to wikipedia, there are 25 billion indexable webpages and
over 100 million websites recorded in 2009, and these
numbers continue to grow. Due to the massive number of
webpages, search engines that search and rank documents
based on their relevances to user queries become essential

Minimizing Recovery State in Geographic Ad Hoc Routing
Arad, N. Shavitt, Y. Sch. of Electr. Eng., Tel Aviv Univ., Ramat Aviv;
This paper appears in: Mobile Computing, IEEE Transactions on Publication

Abstract

Geographic ad hoc networks use position information for routing. They often utilize stateless greedy forwarding and require the use of recovery algorithms when the greedy approach fails. We propose a novel idea based on virtual repositioning of nodes that allows to increase the efficiency of greedy routing and significant ....etc

1.1 Overview
Geographic Information System (GIS) is a computer based information system used to digitally represent and analyse the geographic features present on the Earth' surface and the events (non-spatial attributes linked to the geography under study) that taking place on it. The meaning to represent digitally is to convert analog (smooth line) into a digital form.Every object present on the Earth can be geo-referenced, is the fundamental key of associating any database to GIS. Here, term 'database' is a coll ....etc

Rules of Designing Routing Metrics for Greedy,
Face, and Combined Greedy-Face Routing

Yujun Li, Yaling Yang, and Xianliang Lu




Abstract—


Different geographic routing protocols have different requirements on routing metric designs to ensure proper operation.
Combining a wrong type of routing metrics with a geographic routing protocol may produce unexpected results, such as geographic
routing loops and unreachable nodes. In this paper, we propose a novel routing algebra system to investigate t ....etc
