An Enhanced DV-Hop Localization Algorithm using RSSI
Localization has been identified as a key and challenging topic in Wireless Sensor Networks (WSNs), especially for the applications requiring the accurate position of the sensed information. DV-Hop is a typical range-free node localization algorithm in WSNs; the localization cost and hardware requirements are not high and localization accuracy of sensor nodes is still low under certain circumst...
متن کاملAn Enhanced DV-Hop Localization Algorithm for Wireless Sensor Networks
Obtaining precise location of sensor nodes at low energy consumption, less hardware requirement, and little computation is a challenging task. As one of the well-known range-free localization algorithm, DV-Hop can be simply implemented in wireless sensor networks, but it provides poor localization accuracy. Therefore, in this paper, the authors propose an enhanced DV-Hop localization algorithm ...
متن کاملAn Improved DV-Hop Localization Algorithm Based on Hop Distance and Hops Correction
In order to solve the problem that the DV-Hop algorithm has large error in the network topology environment of random distribution of nodes, this paper proposes a WSN localization algorithm based on hop distance correction. The algorithm uses the method of multi communication radius to correct the hop number within 1 hops, which makes it more consistent with the real situation; Then, the weight...
متن کاملAn Improved DV-Hop Wireless Sensor Network Localization Algorithm
The positioning accuracy is not high for the range-free localization algorithm DV-Hop in wireless sensor networks and the Particle Swarm Optimization algorithm is proposed to optimize the positioning accuracy of the DV-Hop and the IDV-Hop localization algorithm is also proposed. Firstly, the IDV-Hop utilizes DV-Hop to estimate the measuring distances between nodes to be positioned and the beaco...
متن کاملAn Advanced DV-Hop Localization Algorithm for Wireless Sensor Networks
Position information is a fundamental element in WSN. As one of the range-free localization algorithm, the DV-Hop (Distance Vector-Hop) is widely applied. The DV-Hop localization algorithm employs the physical distance between the anchor nodes to estimate the average hop distance, instead of the actual transmission distance. The distance gap between the two kinds of distance undoubtedly leads t...
