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. ER -
