Range free Localization Mechanism using Beacon node Range Level
نویسندگان
چکیده
The mechanism for finding the position of sensor node is crucial for many sensor network applications. Most sensor networks which can tolerate coarse accuracy look range free localization mechanism as its solution. We have proposed a novel algorithm where beacon nodes are randomly distributed and sensor nodes estimates the beacon nodes at different levels according to signal strength. We determine the location of sensor nodes by using this information. We assume the communication range of sensor and beacon nodes are same. The experimental results are encouraging. We found that in our experimental results. The mean localization error (mle) is less than 20% of the communication range. We have shown comparison between the centroid localization algorithm, dv-hop algorithm and our algorithm.
