An 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 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...
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 Improved DV-Hop Localization Algorithm with Reduced Node Location Error for Wireless Sensor Networks
In this paper, we propose a new localization algorithm and improve the DV-Hop algorithm by using a differential error correction scheme that is designed to reduce the location error accumulated over multiple hops. This scheme needs no additional hardware support and can be implemented in a distributed way. The proposed method can improve location accuracy without increasing communication traffi...
متن کاملConstruction of minimum connected dominating set in wireless sensor networks using pseudo dominating set
In a wireless network, messages need to be sent on in an optimized way to preserve the energy of the network. A minimum connected dominating set (MCDS) offers an optimized way of sending messages. However, MCDS construction is a NP-Hard problem. In this paper, we propose a new degree-based greedy approximation algorithm named as Connected Pseudo Dominating Set Using 2 Hop Information (CPDS2HI),...
