摘要：
Sensor localization is a necessary and key functionality for the deployment of wireless sensor network (WSN) applications This paper Investigates on the range-free localization approaches for low hardware requirement A modified DV-Hop localization algorithm is designed to reduce the localization error The modified DV-Hop uses a novel average hop size estimate scheme, in which the local property of hop-size for a particular pair of beacon nodes is considered Simulation results show that the modified DV-Hop algorithm outperforms the original DV-Hop algorithm, especially when the contribution of local hop-size is chosen reasonably
