Sažetak
Localization and tracking of moving target is one of the research focuses of wireless sensor network applications. It has great value in military field. Researchers have proposed many algorithms to complete target localization precisely. Tri-cyclic mutual crosses method based on received signal strength indicator can skip the estimation of transmitting attenuation consumption to locate the target accurately. For the great error happening when the target turns its direction, this paper proposes an algorithm to predict the turning point of its motion path. This method can improve the approximation between depicted and real trajectory, and promote the localization and tracking accuracy of whole system.
