## Abstract:Abstract. Existing localization techniques such as GPS have fundamental limitations which preclude deployment in urban canyons or areas with inconsistent network availability. Augmenting GPS requires specialized infrastructure or tedious calibration tasks which limit general purpose applications. In this paper, we examine the utility of cooperatively sharing location data among connected nodes in order to correct positions with high measurement error in GPS-limited environments. Using simple data sharing and f… Show more

“…The distribution of the anchor position estimates is assumed normal (which is empirically supported in [8]),r k,z ∼ N(r k , K k ). Finally, the letter assumes spatial (over N [1]) and temporal independence for the processes that generate p andr, i.e Σ = diag σ 2 , ..., σ 2 , K = diag {..., K k , ...}.…”

“…Even innovative applications such as cash on delivery (COD) or the use of unmanned aerial vehicles (UAV), require reliable navigation systems for their operation in this type of environment [7]. With regard to military applications as well as search and rescue operations in situations surrounding natural disasters, they have been well received since the beginning of the 21st century [8], [9], [10]. The Department of Defense of the [11].…”

“…The localization server is responsible for estimating the mobile device's position. GPS error modeling in [19] focuses on localization accuracy by creating a collaboration among mobile nodes that are capable of localizing themselves using GPS or pedestrian dead reckoning. A simulation study in [19] uses a simple random mobility model and shows that the magnitude of GPS error can range up to several tens of meters.…”
