A Hybrid Mobile Node Localization Algorithm Based on Adaptive MCB-PSO Approach in Wireless Sensor Networks

A 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...

An Adaptive LEACH-based Clustering Algorithm for Wireless Sensor Networks

LEACH is the most popular clastering algorithm in Wireless Sensor Networks (WSNs). However, it has two main drawbacks, including random selection of cluster heads, and direct communication of cluster heads with the sink. This paper aims to introduce a new centralized cluster-based routing protocol named LEACH-AEC (LEACH with Adaptive Energy Consumption), which guarantees to generate balanced cl...

A Novel Hybrid Node Localization Algorithm for Wireless Sensor Networks

Node self-localization is one of the supporting technologies in Wireless Sensor Networks (WSNs). In this study, a distributed hybrid localization algorithm based on divide-and-conquer and refinement method is proposed. Firstly, the effect of ranging error in the Received Signal Strength (RSS) model on node localization is analyzed and the topology relations of anchors and unknown nodes are deri...

Hybrid Localization Algorithm of Mobile Nodes in Wireless Sensor Networks

—To improve algorithm compatibility and reduce localization errors and node energy consumption, a hybrid localization algorithm of mobile nodes in wireless sensor networks (HLA) is proposed. In HLA, each mobile node analyzes the locations and number of adjacent stationary nodes. When a mobile node has detected that more than two adjacent stationary nodes exist, it will use energy localization ...
