Improve range-free localization accuracy in wireless sensor network using DV-hop and zoning
In recent years, wireless sensor networks have drawn great attention. This type of network is composed of a large number of sensor nodes which are able to sense, process and communicate. Besides, they are used in various fields such as emergency relief in disasters, monitoring the environment, military affairs and etc. Sensor nodes collect environmental data by using their sensors and send them...
متن کاملA multi-hop PSO based localization algorithm for wireless sensor networks
A sensor network consists of a large number of sensor nodes that are distributed in a large geographic environment to collect data. Localization is one of the key issues in wireless sensor network researches because it is important to determine the location of an event. On the other side, finding the location of a wireless sensor node by the Global Positioning System (GPS) is not appropriate du...
متن کاملOn improving APIT algorithm for better localization in WSN
In Wireless Sensor Networks (WSNs), localization algorithms could be range-based or range-free. The Approximate Point in Triangle (APIT) is a range-free approach. We propose modification of the APIT algorithm and refer as modified-APIT. We select suitable triangles with appropriate distance between anchors to reduce PIT test errors (edge effect and non-uniform placement of neighbours) in APIT a...
متن کاملUltrasonic Sensor Network: Target Localization with Passive Self-Localization
A flying robot is localized using ultrasonic sensor network distributed on the ground. This requires localization of sensor nodes first. In absence of RF link between target and sensors, weighted Multi-Dimensional Scaling (MDS) with Gradient Descent is used to localize the sensors from outlier free data obtained from generating a locally linear manifold. After initialization, an Extended Kalman...
متن کاملGeometrical Deformation Analysis of Gotvand-Olya Dam Using Permanent Geodetic Monitoring Network Observations
In this paper, two-dimensional deformation analysis of the Gotvand-Olya dam is done using daily, monthly, seasonal and annual displacement vectors derived from permanent observations of the dam geodetic monitoring network. The strain tensor and its invariant parameters like dilatation and maximum shear are computed as well. Nonlinear finite element interpolation based on C1 Cubic Bezier int...
