Aiming at the problem that the most existing fault diagnosis methods could not effectively
recognize the early faults in the rotating machinery, the empirical mode decomposition, fuzzy …

Densely deployment of various small-cell base stations in cellular networks to increase
capacity will lead to heterogeneous networks (HetNets), and meanwhile, embedding the …

In the clustering method, the cluster head node loses much energy between transmissions
to the base station, confirming that determining the cluster heads is crucial. A robust …

Big data sensing system (BDSS) plays an important role in the Internet of Things, in which
how to reduce power consumption is one crucial problem. Currently, low energy adaptive …

Abstract Recently, Wireless sensor networks (WSNs) have become very popular research
topics which are applied to many applications. They provide pervasive computing services …

The infrastructure of wireless sensor networks (WSN) is structured in an ad-hoc manner and
organized nodes reporting the events to the Base Station (BS). A WSN is integrated with …

One of the most effective approaches to increase the lifetime of wireless sensor networks
(WSNs), is the use of a mobile sink to collect data from sensor. In WSNs, mobile sinks …

A wireless sensor network consists of a large number of nodes, sending sensed data to the
base station or sink, either directly or through intermediate nodes. Multi-hop communication …

Bat algorithm (BA) is a novel population-based evolutionary algorithm inspired by
echolocation behavior. Due to its simple concept, BA has been widely applied to various …

Data collection through mobile sink (MS) in wireless sensor networks (WSNs) is an effective
