AB  - IEEE 802.15.4 is a WPAN (Wireless Personal Area Network) standard 
  which is designed for short range communication. Wireless sensor networks use 
  this standard for its communication. Most of these networks are battery operated. 
  So, power resource has to be properly utilized to balance network performance. 
  This standard follows blind random backoff contention mechanism which turns 
  off the transceiver when it does not have data to transmit. Such, a design creates 
  Hidden Node Collision (HNC) in a network which degrades network performance 
  it terms of throughput, packet delay and power consumption. In this study, a 
  new technique has been proposed in grouping strategy to mitigate the Hidden 
  Node Collision (HNC) problem. Additionally, it introduces beamforming technique 
  to conserve energy in the network. Simulations illustrates that proposed research 
  not only avoids HNC problem but also outperforms IEEE 802.15.4 standard and 
  previous grouping strategies.
