An Adaptive Hybrid Localization Algorithm for Wireless Sensor Network

Aiming at that bounding box algorithm´s coverage is depend on the anchor nodes density in network and DV-Hop has a larger location error, this paper presents a hybrid algorithm that combines the bounding box localization algorithm and DV-Hop localization algorithm, which is called BDV-Hop algorithm. Simulating in MATLAB platform, we analyze bounding box, DV-Hop and the BDV-Hop algorithm respectively. Extensive simulation show that under a variety of network conditions, BDV-Hop algorithm inherits both the advantage of bounding box that has smaller location error and cost, and the advantage of DV-Hop that has high location coverage. At the same time BDV-Hop algorithm have a better adaptability.
