AB  - Relay nodes are used in the transfer of the data packets to 
  the Base Station (BS) via the Sensor Nodes (SN). The placement of RNs influences 
  the lifetime and connectivity of a Wireless Sensor Network (WSN) System. A traffic 
  aware random deployment technique for the relay nodes is proposed in this study. 
  The scalability and traffic of the WSN are analyzed. A traffic aware RN selection 
  is performed for both single hop and multi hop communication cases. Traffic 
  based random deployment methods of RN, namely, lifetime-oriented deployment 
  and hybrid deployment, solve the issue of a short WSN lifetime and insufficient 
  energy utilization. The trade-off between the lifetime extension and connectivity 
  of SN in a WSN is considered in the performance analysis. The proposed method 
  provides an efficient approach for the placement of RNs in a heterogeneous WSN.
