Abstract
Knowing the accurate location of nodes in wireless sensor networks (WSN) is a major concern in many location-dependent applications. Especially in agricultural monitoring, accurate location of the affected crop is required for effective use of fertilizers or pesticides. Low-cost and accurate localization algorithms need to be developed for such applications. Range-free localization like DV-Hop has become popular over the years due to its simplicity and that too without complicated hardware. This paper proposes a modified DV-Hop algorithm that improves the accuracy of localization, based on weights of anchors. In this algorithm, fuzzy logic is used to determine the weights of anchors. Simulation results also show that the proposed algorithm improves localization accuracy with respect to DV-Hop algorithm and its variants.
