Fault-Tolerant Relay Node Placement in Wireless Sensor Networks for Surveillance of Overhead Transmission Lines

Algorithm 1

Dynamic optimal deployment placement.

	Require: , observation , threshold time , and other parameters including location vector
Ensure: optimal backup location vector with N-1
(1)	Initial location vector ;
(2)
(3)	whiledo
(4)	When a fault occurs, we access parameters including , .
(5)	Compute the optimal location with (15) and output ,
(6)	Update the backup location adaptively and configure the backup nodes
(7)	end while
(8)	Output , and for the step 1.
