Sensor Node Placement in Wireless Sensor Network Based on Territorial Predator Scent Marking Algorithm

Pseudocode 1

Pseudocode for territorial-predator-scent-marking-algorithm- (TPSMA-) based sensor nodes placement.

Number of monitored location, 𝑖=1,2,…,𝑆

Number of potential location for sensor node, 𝑗=1,2,…,𝑃

Step  1: check if there is a sensor node located in 𝑗

if yes 𝑥_𝑗=1

else 𝑥_𝑗=0

Repeat Step  1 until 𝑗=𝑃

Step  2:

Compute coverage level to location 𝑖, 𝑓(𝑥) for all respective 𝑗

Mark territory for sensor nodes in j that has the maximum

coverage level to 𝑖 (Scent marking by predator on the area

that has the highest food resources)

Repeat Step  2 until 𝑖=𝑆

Step  3:

Monitored locations will be monitored by sensor nodes

that are within their marked territory. (Sensor node

identifies its monitored location through scent matching)
