Question 11)
In a wireless sensor network, a node which are unable to perform an operation, because of power failure and environmental effects is known as
  • failed node 
  • anormal node 
  • selfish node 
  • badly failed node
Question 12)
A dumb node

  • Home automation networking 
  • Networked Smart Field devices 
  • All of these
Question 15)
“INTSEM controls the transmission rate of a node by adjusting
  • a node’s sleep time 
  • a node’s receiving rate
  • a node’s data transmission rate 
  • the bandwidth of the channel
