摘 要：Wireless sensor networks require energy-efficient and robust routingprotocols.Most routing protocols for sensor networks try to extendnetwork lifetime by minimizing the energy consumption,but have not taken the network reliability into account.In this paper,we analyze the fault models and propose an ENergy-aware FAult-tolerantRouting scheme,termed as ENFAR.Firstly a link-based uniform fault model is presented,and we adopt a cross-layer design to measurethe transmission delay so as to detect the failed nodes.
