Traffic Based Random Deployment of Relay Nodes in Wireless Sensor Networks

Authors : K. Ramalakshmi and K. Thanushkodi

Abstract: 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.
