Internet of Things (IoT) plays an important role in various applications such as industrial control system, environmental monitoring, fire detection, smart home and much more. In today’s scenarios data transmission in emergency rescue is a challenging issue with respect of energy efficient. In this paper, an Energy Efficient Emergency Rescue Scheme (EEERS) is proposed and evaluated which transfers reliable data with high speed and minimum delay in the field of IoT. The simulation is done on MATLAB on different size of network 100–500 sensor nodes. Proposed routing scheme EEERS is compared with existing routing protocols SAR and SPEED on different parameters namely end-to-end delay, throughput, energy consumption, packet loss and packet delivery ratio. Simulation results show that EEERS minimizes end-to-end delay 30–35%, increases throughput 40–42%, reduces energy consumption 50–55%, minimizes packet loss 60–65% and enhances packet delivery ratio 36–40% in emergency rescue environment of IoT. EEERS works on large size of network and prolongs network lifetime.

物联网（IoT）在各种应用中起着重要作用，例如工业控制系统，环境监控，火灾探测，智能家居等。在当今的场景中，就节能而言，紧急救援中的数据传输是一个具有挑战性的问题。在本文中，提出并评估了一种节能高效的应急救援方案（EEERS），该方案可以在IoT领域以最快的速度和最小的延迟传输可靠的数据。在不同大小的网络100–500个传感器节点上的MATLAB上进行了仿真。将提议的路由方案EEERS与现有的路由协议SAR和SPEED在不同的参数（即端到端延迟，吞吐量，能耗，数据包丢失和数据包传输率）上进行了比较。仿真结果表明，EEERS将端到端延迟最小化了30％至35％，吞吐量提高了40％至42％，在物联网紧急救援环境中，可将能耗降低50-55％，将数据包丢失最小化60-65％，并将数据包传输率提高36-40％。EEERS可在大型网络上工作并延长网络寿命。
