(English Abstract)
The majority of localization algorithms assume the anchor nodes are deployed in a square. However, the anchor nodes are likely to be deployed randomly. Both WCL and WMRL, these algorithms using weight value which is estimated by the strength of received signal have limitation. The limitation is that the anchor nodes must be placed in a square. In this paper, we proposed a localization algorithm that can calculate the position of nodes regardless of the limitation. In the proposed algorithm, a sensor node detects a beacon signal of multiple beacon signals emitted by an anchor node and it estimates the pseudo range between the anchor and beacon node. Lastly, it calculates its position by using trilateration. The simulation results show that the algorithm twice outperforms WCL and WMRL in an ideal environment. Furthermore, the proposed algorithm is better performance than DV-hop and WMRL, about 6% and 16% respectively in a noisy environment.
