A Wireless Sensor and Actor Network (WSAN) is a group of wireless devices with the ability to sense physical events (sensors) or/and to perform relatively complicated actions (actors), based on the sensed data shared by sensors. This paper presents design and implementation of a simulation system based on Deep Q-Network (DQN) for mobile actor node control in WSANs. DQN is a deep neural network structure...
This paper presents a new approach of clusteringmechanism in the wireless sensor networks. In our proposedapproach the selection of the cluster head is based on multiplecriteria by combining varieties of performance metrics. Therefore, the main aim of this paper is to enhance the election of themost performed node in order to be a cluster head. The proposedmechanism is evaluated by Matlab and was...
In wireless sensor networks, sensors typically aim to transmit their own readings to the sink node. Constructing an efficient data collection tree is very important since it can determine the lifetime of the given WSNs. In literature, may studies have investigated this issue and proposed algorithms for mobile sink to visit each sensor such that the readings of the sensors can be directly transmit...
In wireless sensor networks (WSNs) energy balancing and energy efficiency are the key requirements to prolong the network lifetime. In this paper, we investigate the problem of energy hole, where sensor nodes located near the sink or in some other parts of the network die very early due to unbalanced load distribution. Moreover, there is a dire need to utilize the energy resource efficiently. For...
Wireless rechargeable sensor networks are becoming crucial and important in recent years for the advancement of wireless energy transmission technology. The previous research shown that not all of sensors can be recharged due to the limitation of energy capacity that mobile chargers can carry. If a sensor playing a critical role in a sensing task cannot function as usual due to the exhausted energy,...
Wireless sensor networks (WSNs) are extensively used in various industries and environments to monitor an environment and manage risks in situations such as real-time traffic monitoring and health care. The Internet of Thing (IOT) is a wireless sensor networks. Because a WSN is an open wireless communication network, it is vulnerable to security threats and attacks. It must authenticate its partner’s...
Barrier coverage is known as one of the most important applications in wireless sensor networks. Most existing studies adopted the Boolean Sensing Model (BSM) which assumes that sensor can detect the object falling in the sensing range of that sensor. Another sensing model, called Elfes Sensing Model (ESM), which assumes that the probability of sensing is a probabilistic value depending on the distance...
In Japan, since aging population and declining birth birthrate are advancing, most of the local areas are suffering from depopulation [1][2]. The decrease of economic activity is deriving poor social infrastructure such as bad road conditions and challenged information communication infrastructure. For those reasons, it is very difficult to keep the lives and properties of the residents in local areas...
Localization systems for outdoor areas using GNSS based systems (like GPS, GLONASS and more) are nowadays widespread and commonly-available in devices like smartphones. For indoor localization, on the other hand, several methods has been proposed in the latest years, like inertial navigation systems (INS) or wireless positioning systems (WPS, like wireless trilateration or fingerprinting methods),...
