Random graph models for the web graph
نویسندگان
چکیده
One of the most extensively researched real-world networks is the web graph. The web graph has vertices representing web pages, with edges corresponding to the links between pages. We describe some of the key properties of the web graph and propose models to simulate its evolution. We survey more recent work on geometric models, where nodes occupy some geometric space and edges are created via a mix of preferential attachment and geometric distance.

Secure Communication in Shotgun Cellular Systems
In this paper, we analyze the secure connectivity in Shotgun cellular systems (SCS: Wireless communication systems with randomly placed base stations) by Poisson intrinsically secure communication graph (IS-graph), i.e., a random graph which describes the connections that are secure over a network. For a base-station in SCS, a degree of secure connections is determined over two channel models: ...
متن کاملFinding Community Base on Web Graph Clustering
Search Pointers organize the main part of the application on the Internet. However, because of Information management hardware, high volume of data and word similarities in different fields the most answers to the user s’ questions aren`t correct. So the web graph clustering and cluster placement in corresponding answers helps user to achieve his or her intended results. Community (web communit...
متن کاملdesigning and implementing a 3D indoor navigation web application
During the recent years, the need arises for indoor navigation systems for guidance of a client in natural hazards and fire, due to the fact that human settlements have been complicating. This research paper aims to design and implement a visual indoor navigation web application. The designed system processes CityGML data model automatically and then, extracts semantic, topologic and geometric...
متن کاملLPKP: location-based probabilistic key pre-distribution scheme for large-scale wireless sensor networks using graph coloring
Communication security of wireless sensor networks is achieved using cryptographic keys assigned to the nodes. Due to resource constraints in such networks, random key pre-distribution schemes are of high interest. Although in most of these schemes no location information is considered, there are scenarios that location information can be obtained by nodes after their deployment. In this paper,...
متن کاملA model for specification, composition and verification of access control policies and its application to web services
Despite significant advances in the access control domain, requirements of new computational environments like web services still raise new challenges. Lack of appropriate method for specification of access control policies (ACPs), composition, verification and analysis of them have all made the access control in the composition of web services a complicated problem. In this paper, a new indepe...
متن کاملSampling from social networks’s graph based on topological properties and bee colony algorithm
In recent years, the sampling problem in massive graphs of social networks has attracted much attention for fast analyzing a small and good sample instead of a huge network. Many algorithms have been proposed for sampling of social network’ graph. The purpose of these algorithms is to create a sample that is approximately similar to the original network’s graph in terms of properties such as de...
