Mobile user locating mechanism based on network latency
نویسندگان
چکیده
A mechanism for the positioning of mobile user location is presented in this paper. Based on the three-point problem from land surveying, this positioning mechanism makes use of network delay to estimate user locations by trigonometry and analytical geometry. Location-sensitive wireless services and applications can be provided without the need of obtaining access to the physical layer information such as signal strength, time of arrival (TOA), angle of arrival (AOA) or adding GPS (Global Positioning System) hardware. It also provides better protection for user privacy by user initiation mechanism. The novel concept of virtual location based on network latency is introduced to investigate the relative topologies among mobile users and positionknown servers.

متن کاملPermanent Network Representation for Mobile User
The network congestion is currently gowing up in the Internet. This problem is especially important in mobile computing due to low duration of connections. We propose an architecture based on mobile agent concepts. This solution provides a permanent representation of a mobile user on the network even when the user is disconnected. Moreover, the representation is also mobile to be continually cl...
