Upper bounds on position error of a single location estimate in wireless sensor networks

Abstract: This paper studies upper bounds on the position error for a single estimate of an unknown target node position based on distance estimates in wireless sensor networks. In this study, we investigate a number of approaches to confine the target node position to bounded sets for different scenarios. Firstly, if at least one distance estimate error is positive, we derive a simple, but potentially loose upper bound, which is always valid. In addition assuming that the probability density of measurement noise is non… Show more

“…The CRLB analysis was also conducted in [43] to quantify the effects of reference errors on the localization performance. In contrast to the lower bound, an upper bound was derived in [44] for different types of measurement errors. In [45], the concept of information coupling was proposed for cooperative network localization.…”

“…All these research efforts provide valuable references for the wireless localization and tracking design in terms of system optimization [47], [48], [49], [51], [52], [53], algorithms development [42], [57], [58], [59], [60], performance limits [38], [40], [41], [43], [44], [45], [46] and environmental experiments [61], [62], [63], with various measurement choices and practical constraints (e.g., indoor [67], outdoor [68], mobile tracking [42], non-line-of-sight [39], [40], [41] and limited energy budget [18], [19], [20]). However, there is no relevant work on the investigation of the EP philosophy for the SLAT scheme in WSNs, particularly in environments with the spatial-temporal-domain random measurement accuracy.…”

“…This kind of business environment is significantly different from the modern retail channel, where product and brand choices are influenced by formal mechanisms such as store merchandising and online/offline advertising [7] Knowledge of the limits of a customer's spending (budget constraints) helps managers avoid overspending on customers who have a low ceiling and underspending on customers who have a high ceiling. In the CPG setting, consumers tend to purchase assortments of products/brands in a shopping trip, thus leading to the multiple discreteness problem [8]. The purchase motives of nanostore consumers consist of product attributes, self-orientation, and service guarantees.…”

“…The error bound is another and less demanding way to describe the property of measurement error. The bounded error assumption has been widely applied in many areas, e.g., set-theoretic estimation in system and control area [19]- [21], wireless localization [22], [23], etc. Moreover, compared with the statistical distribution of measurement error, it is much easier to obtain the measurement error bound in many situations [24].…”
