Abstract
AbstractThe rapid expansion demand of sensor devices have attained significant attention for wireless sensor network (WSN) and demands many Internet of Things (IoT) applications for real-time usage. The routing technique must capable of efficiently delivering packets to sink to achieve large-scale IoT application’s reliability. How to guarantee real-time emergency reaction capabilities during data transmission is now a difficult topic for research under the demand of large IoT network scale expansion. Existing routing scheme fails to deliver data and has higher routing latency due to transmissions failures and lower energy nodes. In this article, an energy efficient emergency response routing scheme (EEER) is proposed. The proposed EEER delivers the critical data efficiently under the emergency with lower latency. Extended transmission range covers wide range of intermediate nodes for data communication. This scheme selects nodes with higher residual energy for forwarding emergency data towards sink. To ensure this, the output of the proposed device is validated with an comprehensive simulation test. Results tested using NS2 simulation method indicate an improvement of 5% decrease in energy usage, 6% increase in packet delivery ratio and 7% decrease in end to end delay.KeywordsEnergy awareLatencyEmergency dataInternet of Things
