چکیده

In this paper, we study the geographic properties of Internet routing. Our work is distinguished from previous studies of Internet routing in that we consider the geographic path traversed by packets, not just the network path. We examine several geographic properties including how circuitous Internet routes tend to be, how multiple ISPs along an endto-end path share the burden of routing packets, and how much sharing there is between paths at the geographic level. We evaluate these properties using extensive network measurements. We examine both the spatial and the temporal variations of some of the properties. We discuss the implications of these geographic properties and conclude that geography is an interesting tool for analyzing the Internet properties. Keywords— Network measurement, Internet topology, routing, geography

Geographic and Clustering Routing for Energy Saving in Wireless Sensor Network with Pair of Node Groups

Recently, wireless sensor network (WSN) is the popular scope of research. It uses too many applications such as military and non-military. WSN is a base of the Internet of Things (IoT), pervasive computing. It consists of many nodes which are deployed in a specific filed for sense and forward data to the destination node. Routing in WSN is a very important issue because of the limitation of the...

Advanced operations research techniques for multi-constraint QoS routing in internet

Internet Traffic has grown exponentially over last few years due to provision of multiple class services through Internet backbone. With the explosive use of Internet, contemporary Internet routers are susceptible to overloads and their services deteriorate drastically and often cause denial of services. In this paper, an analysis is made how forecasting technique, routing algorithm and Genetic...

On the spatial properties of internet routes

The geographic layout of the physical Internet inherently determines important network properties and traffic characteristics. In this paper, we examine the spatial properties of the Internet topology and routing. To represent the network we conducted a geographically dispersed traceroute campaign, and embedded the extracted topology into the geographic space by applying a novel IP geolocalizat...

On Inferring the Geographic Properties of the Internet

Acknowledgments This M.S. thesis is a collection of two pieces of work done under the guidance of Dr. Venkata N. Padmanabhan at Microsoft Research and Prof. Randy H. Katz. The first piece of work is on IP-Geography Mapping. I worked on this problem as an intern at Microsoft Research under the mentor-ship of Venkata Padmanabhan. Later, we studied the Geographic Properties of Internet Routing. Th...
