A localization system based on DV-Hop localization algorithm and RSSI ranging technique
基于DV-Hop定位算法和RSSI测距技术的定位系统

As an assistant localization method, received signal strength indicator (RSSI) ranging module was added into the DV-Hop localization algorithm to resolve its problems existing in experimental environment. In order to implement the localization system, first, the RSSI model was built up; then, this model was applied to control DV-Hop localization process from anchor nodes and nonanchor nodes respectively. It is proved that improved localization system improves system stability and localization precision with a little sacrifice on computing complexity. Therefore, it can be applied into wireless sensor networks.
