Industrial communication track in next generation for fourth revolution industrial process. Adopting fog into systems promising technology within architecture. With Software D...

Optimal sensor placement OSP technique plays a key role in the structural health monitoring SHM of large-scale structures. Based on the criterion of the OSP for the modal test, an improved genetic algorithm, called “generalized genetic algorithm GGA ”, is adopted to find the optimal placement of sensors. The dual-structure coding method instead of binary coding method is proposed to code the so...

The placement of sensors to support security monitoring is obviously critical as it will directly impact the efficacy of allocated resources and system performance. It is critical to be able to observe and monitor the greatest total area possible. In addition, it is necessary to be able to spatially track the movement of people and activities in support of security. It is shown that important a...

The ease of use and re-configuration in a wireless network has played a key role in their widespread growth. The node deployment problem deals with an optimal placement strategy of the wireless nodes. This paper models a wireless sensor network, consisting of a number of nodes, and a unique sink to which all the information is transmitted using the shortest connecting path. Traditionally the sy...

In this paper, a method for sensor placement to improve the placement quality based on angle of arrival of signal in a specific area is proposed. The installation place of sensors may be constrained with specified boundaries. In this method, the criterion of maximum quality of placement is the Cramer-Rao bound. The generalized pattern search as an effective method is used to maximize error boun...

Wireless sensor networks are subject to failures. Deployment planning should ensure that when a data sink or sensor node fails, the remaining network can still be connected, and so may require placing multiple sinks and relay nodes in addition to sensor nodes. For network performance requirements, there may also be path-length constraints for each sensor node. We propose four algorithms, Greedy...

Wireless Sensor Network (WSN) is pertinent to many applications with varied network parameters. Sensor node placement in the application region whether it is indoor or outdoor is a major task as well as plays very remarkable role in the network performance. Node placement is carried out according to the region where it is applied, either deterministic or non deterministic. Because of the need f...

A risk-based sensor placement methodology is proposed to solve the problem of optimal location of sensors to protect population against the exposure to, and effects of, known and/or postulated chemical, biological, and/or radiological threats. Risk is calculated as a quantitative value representing population at risk from exposure at standard exposure levels. Historical meteorological data are ...

In this paper, we study the problem of network deployment in hybrid sensor networks, consisting of both resource-rich and resourceimpoverished sensor devices. The resource-rich devices, called microservers, are more expensive but have significantly greater bandwidth and energy capabilities compared to the low-cost, low-powered sensors. Such hybrid sensor networks have the potential to support t...
