GPS-Less Low Cost Outdoor Localization for Very Small Devices.
- IEEE Personal Communications Magazine,
, 2000
"... Abstract-Instrumenting the physical world through large networks of wireless sensor nodes, particularly for applications like environmental monitoring of water and soil, requires that these nodes be very small, light, untethered and unobtrusive. The problem of localization, i.e., determining where ..."

a given node is physically located in a network is a challenging one, and yet extremely crucial for many of these applications. Practical considerations such as the small size, form factor, cost and power constraints of nodes preclude the reliance on GPS (Global Positioning System) on all nodes
A generalized processor sharing approach to flow control in integrated services networks: The single-node case
- IEEE/ACM TRANSACTIONS ON NETWORKING
, 1993
"... The problem of allocating network resources to the users of an integrated services network is investigated in the context of rate-based flow control. The network is assumed to be a virtual circuit, connection-based packet network. We show that the use of Generalized processor Sharing (GPS), when co ..."

, the performance of a single-server GPS system is analyzed exactly from the standpoint of worst-case packet delay and burstiness when the sources are constrained by leaky buckets. The worst-case session backlogs are also determined. In the sequel to this paper, these results are extended to arbitrary topology

Ad hoc positioning system (APS) using AoA
, 2003
"... AoA(Angle of Arrival) is a well known method used for positioning in providing services such as E911, and for other military and civil radio-location applications, such as sonars and radars. Although devices such as GPS receivers and digital compasses provide good positioning and orientation outdoo ..."

Inertial/GPS System for Seismic Survey
"... This paper describes the Position and Orientation System for Land Survey (POS/LS) that Applanix is developing for land survey applications, initially for seismic surveying. The POS/LS is derived from the Applanix POS product family, and will include Applanix’s next generation tightly coupled inertia ..."

Ad Hoc Positioning System (APS)
- IN GLOBECOM
, 2001
"... Many ad hoc network protocols and applications assume the knowledge of geographic location of nodes. The absolute location of each networked node is an assumed fact by most sensor networks which can then present the sensed information on a geographical map. Finding location without the aid of GPS ..."

Bounds, Approximations And Applications For A Two-Queue GPS System
- In Proceedings of IEEE INFOCOM'96
, 1996
"... In this paper we study Generalized Processor Sharing (GPS) scheduling with Markov Modulated Fluid Sources (MMFSs). We focus on a GPS system serving two classes of customers. By using a combination of the bounding approach and the approximation approach to performance analysis and by taking advantage ..."
