Recovery of Lost Target Using Target Tracking in Event Driven Clustered Wireless Sensor Network
Algorithm 1
Lost target recovery in WSHUN algorithm.
(1) If (!found target) Then | (2) search in past few locations if target is available | (3) Else | Initiate Recovery | (4) Predict next locations as few locations ahead | (5) Wake up all SHNs around this location | (6) If (Found by neighbouring nodes) | (7) If (energy > τ) | (8) Become the CTN and localize target with Trilateration | (9) End if | (10) Send target found message to previous tracking node | (11) Else | (12) Wake up all two hop nodes around this location | (13) Repeat till target is found | (14) End if | (15) End if |
