Recently, the use of the database paradigm has emerged as a feasible solution to manage data in Wireless Sensor Network (WSN) environments. Various Sensor Network Query Processors (SNQPs) implements in-network declarative query processing that provide data reduction, aggregation, logging, and auditing facilities. These SNQPs view the WSN as a distributed database over which declarative query pr...

This paper explores the structural and behavioural similarities that exist between the chemical constitution of natural substances and WSN (Wireless Sensor Network) topology. It introduces Atomic Topology Management (AToM), which uses concepts like WSN electron, WSN nucleus, WSN photon, and WSN atom to model sensor node, base station, message and basic WSN subset consisting of one base station ...

The main tasks of a Wireless Sensor Network (WSN) are data collection from its nodes and communication of this data to the base station (BS). The protocols used for communication among the WSN nodes and between the WSN and the BS, must consider the resource constraints of nodes, battery energy, computational capabilities and memory. The WSN applications involve unattended operation of the netwo...

Wireless sensor networks (WSN) are widely applied in many fields such as e-health, military, surveillance and industrial applications. In e-health field, WSN is commonly used for monitoring elderly people, babies , and patients The progress of WSN technologies allowed the connection of a camera to WSN node to transfer images and video. This technology improves the monitoring of patients and giv...

Wireless sensor networks (WSNs) is becoming a progressively important and a challenging research area. Advancements in WSN enable a wide range of environmental monitoring and object tracking applications. Moreover, multihop routing in WSN is affected by new nodes constantly entering or leaving the network. Therefore, the self-optimized and self-aware mechanism is required to handle the problems...

Network architecture is the foundation of network system. Wireless sensor networks (WSN) are always concentrated some key technologies under specific applications, and some prototype systems are developed according to specific applications of environments, but the research on WSN architecture is relatively weak currently. WSN is a highly complex distributed system, the defects in traditional WS...

A Wireless Sensor Network (WSN) is a distributed system composed of autonomous sensor nodes wireless connected and randomly scattered into a geographical area to cooperatively monitor physical or environmental conditions. Adequate techniques and strategies are required to manage a WSN in order it properly works, observing specific quantities and metrics to evaluate the WSN operational condition...

Applications of wireless sensor network (WSN) are growing significantly, and many security protocols meant for WSN have been proposed. One of the unique problems of WSN is that the sensor nodes are not tamper resistant as the main attraction of deploying WSN is its low cost. Node replication attack exploits this weakness to launch an attack, in which cryptographic secrets from the compromised s...

<p><span>In recent time, the applications' diversity of wireless sensor network (WSN) attracts many researchers. WSN comprises nodes with limited battery power. Therefore, energy consumption should be controlled to optimum. Clustering is an efficient solution for management in WSN, but clustering does not consider sink node location. It will cause hole problem multi-hop routing. Ene...
