Abstract:

Remote tracking for mobile targets is one of the most
important applications in wireless sensor networks (WSNs). A
target tracking protocol– exponential distributed predictive tracking
(EDPT) is proposed. To reduce energy waste and response time,
an improved predictive algorithm–exponential smoothing predictive
algorithm (ESPA) is presented. With the aid of an additive
proportion and differential (PD) controller, ESPA decreases the
system predictive delay effectively. As a recovery mechanism, an
optimal searching radius (OSR) algorithm is applied to calculate
the optimal radius of the recovery zone. The simulation results validate
that the proposed EDPT protocol performes better in terms of
track failed ratio, energy waste ratio and enlarged sensing nodes
ratio, respectively.
