Recovery of Lost Target Using Target Tracking in Event Driven Clustered Wireless Sensor Network
Algorithm 2
Lost target recovery in WSHAN algorithm.
(1) If (target is in range of HBN) Then | (2) Wake up all HBNs | (3) Track the target till in reach (As the target becomes unreachable it is lost) | (4) If (!in range) Then | Initiate Recovery | (5) If (target is in vicinity of three HBNs) Then | (6) If (energy > τ) | (7) Become the CTN and Localize target with trilateration | (8) End If | (9) Send the target found message to previous tracking node | (10) End If | (11) End If | (12) Else If (!found target) | (13) Call (KF/EKF/PF algorithm) | (14) End If |
