摘要

In order to estimate locations of wireless nodes withoutrnGPS devises, various methods to estimate the absolute locationsrnwith help of some wireless nodes whose locationsrnhave already been determined. However, since locationsrnof wireless nodes are estimated independently of the otherrnnodes, the estimated locations do not keep neighbor relationrnamong them. This paper proposes a novel method tornachieve the relative locations of wireless nodes only basedrnon sets of neighbor wireless nodes of all the wireless nodesrnachieved by exchanges of beacon messages with their nodernIDs. Here, the wireless nodes are assumed to be located onrna line, i.e. 1-demensional estimation. By replacing wirelessrnnodes among which their relative locations are not determinedrnonly by the sets of neighbor wireless nodes with anrnaggregate wireless node, the relative locations among thernaggregate wireless nodes are determined with less computationalrncomplexity than the naive method.
