METHOD AND WIRELESS TERMINAL FOR GENERATING AND MAINTAINING A RELATIVE POSITIONING SYSTEM
摘要
Method for determining the relative position of wireless terminals (1) in an ad hoc network, wherein at least some of said wireless terminals can communicate over wireless links (2) in one or several hops with at least some of the other wireless terminals. The following steps are performed in the wireless terminals: measuring in a plurality of said wireless terminals the distances (dij) to one-hop neighbors, using the distances measured in at least two wireless terminals to compute the location (x, y) of at least one other wireless terminals. Advantage: GPS-less positioning in ad hoc networks.
