In this paper, we propose a power saving localization scheme that reduces the localization error at the same level as the conventional scheme and reduces redudant localization packets by considering a node's distance and a maximum localization error of a sensor node.
In our proposed scheme, we set the threshold based on the overlapped area rate and each sensor node inhibits transmitting its localization packet when a neighbor sensor node which is nearer than the threshold transmited a localization packet first.
In addition, in our proposed scheme, by setting the backoff proportional to each sensor node's maximum localization error, the sensor node which has the large maximum localization error inhibits transmitting its localization packet when there is a neighbor sensor node which has less maximum localization error.
In this way, our proposed scheme reduces the number of transmitting localization packets.
By the simulation with NS-2, we evaluate the number of transmitting localization packets, the localization error and the total energy consumption of the conventional scheme and our proposed scheme.
The simulation results show that our proposed scheme can reduce the localization error at the same level as the conventional scheme and reduces the number of transmitting localization packets and the total energy consumption. |
