“…Compared with algorithms in literatures [3][4][5][6], our method considers the differences between 2D plane and 3D space, and uses the degree of coplanarity to rule out the unsatisfactory positioning unit and get the best positioning unit. Compared with literatures [2,[7][8][9], RSSI technology is used and the traditional DV-Distance algorithm is modified.…”

Location information is crucial in the wireless sensor network. The nodes in wireless sensor networks are often deployed in the three-dimensional scenario. Therefore, the three-dimensional localization algorithm has become hot in wireless sensor networks. However, existing 3D localization algorithms have shortcomings, such as high complexity, low positioning accuracy, and great energy consumption. Aiming at the existing problems of the current 3D localization algorithms, an improved 3D localization algorithm based on Degree of Coplanarity (3D-IDCP) is proposed. The concept of coplanarity is added into the traditional DVDistance algorithm to reduce the positioning error caused by anchor nodes which are coplanar. Those unknown nodes which have been located are promoted to assistant anchor nodes to improve the positioning coverage. The simulation results show that the proposed method is accurate in positioning and can enhance the positioning coverage.

Over a wireless sensor network (WSN), accurate localization of sensor nodes is an important factor in enhancing the association between location information and sensory data. There are many research works on the development of a localization algorithm over three-dimensional (3D) space. Recently, the complexity-reduced 3D trilateration localization approach (COLA), simplifying the 3D computational overhead to 2D trilateration, was proposed. The method provides proper accuracy of location, but it has a high computational cost. Considering practical applications over resource constrained devices, it is necessary to strike a balance between accuracy and computational cost. In this paper, we present a novel 3D localization method based on the received signal strength indicator (RSSI) values of four anchor nodes, which are deployed in the initial setup process. This method provides accurate location estimation results with a reduced computational cost and a smaller number of anchor nodes.

Abstract-Wireless sensor node's localization is a funda-mental technology in Wireless Sensor Networks. There are only quite a few study on three-dimensional (3D) localization which is suffered in slow progress, actually, is one of the main difficulties in WSN localization. Based on the study of the existing two-dimensional positioning algorithm and the application of terrain modeling, localization algorithm for sensor nodes in (3D) condition has been focus on as well as the application of terrain model. Using the idea proposed by representative algorithm--APS multi-hop AOA (Angle of Arrival), this paper proposed a new algorithm named Multi-hop Three Dimensional AOA With Space-based Angle Trans-mission (MSAT3D AOA). Using this technology, target nodes can use information of anchor nodes which are more than one hop away form. This paper also combined MSAT3D AOA algorithm with Delaunay triangulation algorithm for terrain modeling.
