An 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 کاملLSDV-Hop: Least Squares Based DV-Hop Localization Algorithm for Wireless Sensor Networks
—Wireless Sensor Networks (WSNs) have increasingly become a hot spot of research and application in the fields of computer networks and telecommunications. It is undoubtedly one of the most important issues for WSNs to search an accurate and effective localization method. In this paper, an improved DV-Hop localization algorithm, called least squares DV-Hop (LSDV-Hop), is proposed based on the ...
متن کاملImprove 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 کاملAn 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 ...
