Query: An Optimize-Aware Target Tracking Method with Combine MAC layer and
  Active Nodes in Wireless Sensor Networks   Wireless Sensor Network WSN is consisted of nodes with different sizes and a
specific goal. Tracking applications are very important in WSNs. This study
proposes a method for reducing energy consumption in WSNs, considering target
tracking. A prediction method is also presented with the help of MAC Medium
Access Control layer in which a few number of nodes are in active mode to track
the target while the rest of the nodes are switched into sleeping mode. Energy
consumption was reduced by decreasing the number of nodes involved in target
tracking and activating merely a limited number of necessary nodes. The
conducted experiments suggest that the proposed algorithm has a much better
performance compared to similar algorithms in different conditions, including
energy consumption in different communication ranges, effect of the number of
nodes on energy consumption, the number of nodes involved in tracking in terms
of communication range, and losing the target. This means the proposed method
is superior and more efficient. When the target enters the simulation area,
nodes of the network identify the target node through the proposed method
(which is the optimum method) and track it as long as it is inside the
simulation area. Performance criteria, including energy, other nodes, and
throughput were used in simulation. The results showed that the proposed method
has the optimum performance and reduces energy consumption of the network
during tracking. The results of the simulation showed that the proposed method
reduces energy consumption to an acceptable extent, compared to previous
methods, in addition to increasing the accuracy of target tracking. Keywords:
Active nodes, MAC layer, Energy efficiency, Target tracking, Wireless sensor
networks, Target tracking.
