摘要：We introduce a system for multiple target range-based localization
systems, such as those based on time-of-arrival (TOA) and received
signal strength indicator (RSSI) for distance measurement estimations.
In order to improve the accuracy of the location estimation for all
target nodes, our system makes use of distance estimations between
target nodes as well as between anchor and target nodes, and weights
for all nodes. We propose variations on two popular localization
algorithms and compare their accuracy against that of the conventional
algorithms using simulations and experiments. Our results show that
our proposal consistently offers a better localization accuracy than
the conventional algorithms.
