Abstract—With the proliferation of the application areas of the
Wireless Sensor Networks (WSNs) and the technological advances in sensor electronics, target tracking has become one of the most important functions in WSNs. The overwhelming majority of moving target tracking studies in WSNs has assumed either onedimensional space (lineland), or two-dimensional domain (flatland). However, many existing, such as environmental monitoring of rugged terrain, structural health monitoring of buildings, underground and underwater WSN applications, and emerging applications, such as search-and-rescue via Micro Aerial Vehicles
(MAVs), reconnaissance by insect-sized flying robots, need target tracking in three dimensional space. In this study, we assume a
Wireless Aerial Sensor Network (WASN) with conventional lowpower and low-complexity features and devise a low spatial and temporal complexity moving target tracking mechanism in 3D based on g-h filter. Our extensive simulations show promising preliminary results for our approach in terms of very low inaccuracy rates between the true location of the target and the sink’s forecasts as well as negligible estimate errors in terms of
Euclidean distance.

V. C ONCLUSION AND F UTURE W ORK
Studies in the literature on tracking moving targets WSNs have assumed either a one-dimensional or two-dimensional space. Recent advances in sensor technology coupled with emerging new areas of WSN applications necessitate that target tracking should also be considered in three dimensional space. In this study, we have devised a simple mechanism based on a low spatial and temporal complexity filtering mechanism to track a moving target in 3D at the sink node by means of measurements supplied by sensor nodes. Our approach is based on the g-h filter as it is known in the field of estimation theory. We have shown by means of extensive simulations that the inaccuracy of our approach under varying parameters is quite low both in terms of percentage in three Cartesian coordinates as well as in Euclidean distance between sink’s estimate and the actual location of the target. It is noteworthy that our simulations also
