无线传感器网络(WSN)中的传感器由于能量耗尽、硬件故障等原因容易发生故障，容错是无线传感器网络的关键问题之一。现有的容错机制要么消耗大量的额外能量来检测故障并从故障中恢复，要么需要使用额外的硬件和软件资源。本文提出了一种新的无线传感器网络能量感知容错机制，称为信息归属路由(IHR)。在我们的IHR中，非簇头节点限制和选择其数据传输的目标。因此，它消耗的能量更少。实验表明，与现有的LEACH和DHR协议相比，我们提出的协议可以显著降低能耗。
Sensors in a Wireless Sensor Network (WSN) are prone to failure, due to energy depletion, hardware failures, etc. Fault tolerance is one of the critical issues in WSNs. The existing fault tolerant mechanisms either consume significant extra energy to detect and recover from the failures or need to use additional hardware and software resource. In this paper, we propose a novel energy-aware fault tolerance mechanism for WSN, called Informer Homed Routing (IHR). In our IHR, the non cluster head nodes limit and select the target of their data transmission. Therefore, it consumes less energy. Our experiments show that our proposed protocol can dramatically reduce energy consumption, compared to two existing protocols, LEACH and DHR.
