—Deployment is an important issue in wireless sensor networks(WSNs). Most of recent researches focus on the optimal deployment patterns for full-coverage WSNs. In practice, there are only finite number of nodes can be used in WSNs applications, which cannot guarantee that the entire region can be monitored; On the other hand, the information generated from monitored objects is distributed uneve...

Wireless Sensor Network (WSN) had become almost an indispensible especially the demand for data acquisition from national security to disaster mitigation management, weather data to environmental changes and from many more agencies. The effectiveness and efficacy of WSN dependent on the strength and weakness of the deployment of the sensor nodes which collect and transmit the data. The success ...

Sensor networks have been applied in a wide variety of situations. Recently directional sensor networks consisting of directional sensors have gained attention. Network life is very crucial parameter for sensor network. In this paer, we use artificial intelligence to deploy sensor node with objective of maximize life of network. Simulation results shows that proposed method perform well. Key Wo...

The designer of a sensor network protocol needs to address several low-level details such as message collisions, message losses, and resource limitations. Also, the designer needs to solve several high-level problems such as routing, leader election, and diffusing computation that are already considered in distributed systems and traditional networking. Therefore, to simplify the design of sens...

The use of large-scale wireless sensor networks in road monitoring systems has been the subject of much recent research, particularly with regard to the issue of how sensors can be efficiently placed in order to reduce network costs while maintaining the required performance. In this paper, we propose an optimal sensor deployment scheme enabling complete road surface coverage with a minimum num...

This paper presents a new Ubiquitous Sensor Network (USN) Architecture to be used in developing countries and reveals its usefulness by highlighting some of its key features. In complement to a previous ITU proposal, our architecture referred to as "Ubiquitous Sensor Network for Development (USN4D)" integrates in its layers features such as opportunistic data dissemination, long distance deploy...

Sensor is an important part of an automatic system. Wireless Sensor Network (WSN) is a system consisting of large number of Sensor Nodes (SNs) geographically distributed in the region to be monitored. Placement of SNs in the region to be monitored is the major factor that determines the life, coverage area and connectivity of WSN. Because of the limited sensing range of SN, most of the events c...

Mobile robots used for coverage and exploration is an important field crucial for tasks such as mine clearing, intrusion detection, sensor deployment, search-and-rescue, and harvesting. In this paper, we cover existing approaches and the evolution of the field. We identify the primary existing techniques, including cellular decomposition, heuristics, insect-based coordination, and multi-robot s...
