Toward a Measurement-Based Geographic Location Service
نویسندگان
چکیده
Location-aware applications require a geographic location service of Internet hosts. We focus on a measurement-based service for the geographic location of Internet hosts. Host locations are inferred by comparing delay patterns of geographically distributed landmarks, which are hosts with a known geographic location, with the delay pattern of the target host to be located. Results show a significant correlation between geographic distance and network delay that can be exploited for a coarse-grained geographic location of Internet hosts.

Two-Tier Geographic Location of Internet Hosts
Multimedia delivery systems, such as Content Distribution Networks (CDNs), improve by knowing the geographic location of their clients. Therefore, we focus on a measurement-based geographic location service of Internet hosts. Such a service infers host locations from delay measurements taken from probe machines toward landmarks, which are hosts with a known geographic location, and the host to ...
متن کاملSink Location Service Based on Fano Plane in Wireless Sensor Networks
Sink location is considered as a basic service in geographic routing in wireless sensor networks. Obtaining the location of sink node by source node using an efficient method with low complexity has always been a challenging issue in research. In this paper, a sink location algorithm based on Fano plane is proposed. The research challenge is how to ensure the intersection of two SLQ (Location Q...

متن کاملGLS : a Location Service for an Ad Hoc Network
The Grid Location Service (GLS) is a location service which provides location information for a node in a mobile ad hoc network. GLS provides a mechanism for a node to track the location of other nodes in the network topology. A mobile ad hoc network (MANET) is an autonomous system of mobile routers (and associated hosts) connected by wireless links–the union of which form an arbitrary graph. T...
