An Enhanced HCRL Algorithm in Wireless Sensor Networks for Pervasive Computing

HCRL is a localization algorithm in Wireless Sensor Networks, which can fix the position of the unknown node with a single flooding broadcast. This algorithms can save on the traffic of the system, meanwhile has superior computational complexity and lower accuracy of localization. In this paper, we enhance HCRL algorithms by setting the threshold of isodynamic point. After enhancing, IMP-HCRL algorithms reduce the computational complexity of the HCRL, and increase the accuracy of localization by 3.23%.
