Hierarchical architecture is an effective scheme to make wireless sensor networks (WSNs) scalable and energy-efficient. Clustering the sensor nodes is a well-known two-layered architecture suitable for WSNs and has been extensively explored for different purposes and applications. In this paper a novel clustering approach called the adaptive competition-based clustering approach (ACCA) is proposed for WSNs. Selecting the cluster heads in the proposed ACCA is performed based upon a hybrid of local competition and the distances among the cluster heads. First, by the new proposed competition scheme, the nodes which are with the high residual energy and closer to the centre of the density of the nodes are elected and form an initial set of cluster head candidates. Then the candidates with suitable distances to other neighbor candidates are elected as the cluster heads. The proposed algorithm is fast with a low time and message complexity. It offers a longer lifetime for the networks, and at the same time, a proper level of fault tolerance. The proposed ACCA is simple enough to be implemented in real systems. Different simulation experiments are performed on different states and the algorithm is compared with some well-known and related clustering approaches. The experiments suggest that in terms of longevity and fault-tolerance, ACCA out-M. Afsar (B)

“…Although the proposed method aimed at control system, it still has great referential significance for the fault-tolerant measurements of multisensor systems. Some other scholars proposed a cluster-based fault-tolerant protocol [24], which utilized energy-saving technology to cluster and proposed a new error detection mechanism with high accuracy.…”

A cooperative estimation algorithm is proposed for mutli-sensor networks with imprecise measurements caused by electromagnetic interferences, abnormal currents and other faults in the multi-sensor measurement process. Adaptive schemes based on a reference model are introduced to overcome the adverse effects of multiplicative interference on the estimated information. Then, rigorous theoretical proofs are developed to analyze the adaptive estimation algorithm. Finally, numerical simulation results are carried out to verify the effectiveness of the theoretical analysis.

Internet of Thing (IoT) computing is an environment where various devices with sensors and actuators are connect, and interact together to acquire contexts and provide useful services. With the advances of IoT technologies, its usability becomes an in important issue. However, there exist various types of faults in IoT computing which are not conventionally addressed in software research community. Providing reliable IoT services is challenging. In this paper, we present a hierarchy of IoT faults and analyze causes and symptoms of the faults. Based on the analysis, we define effective methods for managing IoT faults. We believe that our proposed framework for managing IoT faults can be utilized in reducing the development cost of IoT applications and enhancing the quality of the applications.
