Distributed Localization in Wireless Sensor Networks: - Quantitative Comparison Koen (Correct)
....measure the distance between directly connected nodes in the network. From a cost perspective it is attractive to use the RF radio for measuring the range between nodes, for example, by observing the signal strength. Experience has shown, however, that this approach yields poor distance estimates [14]. Much better results are obtained by timeof flight measurements, particularly when acoustic and RF signals are combined [12,15] accuracies of a few percent of the transmission range are reported. Our simulation results provide insight into the e#ect of the accuracy of the distance measurements ....

....et al. 9] It is also ultrasound based, but less costly and less accurate. 98 AZONDEKON et al. It is worth discussing the use of RF signal strength for the purpose of physical location sensing. Two such location systems are RADAR, by Bahl and Padmanabhan [1] and SpotON, by Hightower et al. [7]. RADAR uses an 802.11 infrastructure wireless local area network and scene analysis or triangulation. SpotON is an ad hoc location sensing system. In contrast to the other approaches, RF location sensing systems are probabilistic. Foundation work has been done by Seidel and Rapport [11] All the ....

....valid would be prone to error. These problems led us to consider alternate methods that would (a) scale gracefully to a large number of AP s and (b) let us readily incorporate physical and logical properties of the environment in the geolocation computation. A hillclimbing method of geolocation [HWB00] which generates a sequence or set of guesses that are checked against a measure of quality (e.g. minimal error) seemed natural. Against our criterion of scaling, hillclimbing is advantageous because computing the location is fast (a guess) and computing its error is linear in the number of ....

....proposed that allows nodes to estimate and map relative angles between neighbors [26] Similar to TOA and TDOA, AOA estimates require additional hardware not available or likely to exist on sensor network devices. Received Signal Strength Indicator (RSSI) technology such as RADAR [1] and SpotOn [14] has been proposed for hardware constrained systems. In RSSI techniques, either theoretical or empirical models are used to translate signal strength into distance estimates. For RF systems [1] 14] problems occur as multi path fading, background interference, and irregular signal propagation ....

....distance measurements with asserted positions (of sensors) creates a multilateration system like AT T s Bats. Combining proximity measurements with asserted position 2 yields an Active Badge style system. Using only distance measurements results in an ad hoc lateration system like SpotON [11]. Any of these systems could be augmented to compute object orientation by adding angle measurements from an on board digital compass or perhaps simply by inferring that an infrared badge only points forward. In general , every object s location consists of a position, orientation, and time. 3. ....
