As the usage and development of wireless sensor networks increases, problems related to these networks are becoming apparent. Dynamic deployment is one of the main topics that directly affects the performance of the wireless sensor networks. In this paper, biogeography-based optimization is applied to the dynamic deployment of static and mobile sensor networks to achieve better performance by t...

Underwater pollution incidents occur frequently, and obtaining accurate information about their exact location real-time situation is helpful for promptly formulating plans to contain mitigate the situation. Autonomously adjusting position of sensors optimal coverage monitoring regions interest (e.g., oil spill zones, chemical contamination areas) in real time a significant challenge. To this e...

The wireless sensor networks (WSN) is a research area in continuous evolution with a variety of application contexts. Wireless sensor networks pose many optimization problems, particularly because sensors have limited capacity in terms of energy, processing and memory. The deployment of sensor nodes is a critical phase that significantly affects the functioning and performance of the network. O...

Now a day’s, it has been a great idea of research on using Wireless Sensor Networks (WSNs) to assist in the initial deployment of sensor nodes. Hole problem in WSNs is the most fundamental Problem in WSNs. Hole means a communication gap in WSNs. Finding an optimal sensor deployment strategy that would minimize the cost, reduce the node failure and also reduce the communication overhead. Then it...

The industrial world is currently considering the adoption of Wireless Sensor Networks (WSN) for industrial process and control applications. However, when using wireless sensor networks in such application scenarios, network performance, reliability, and robustness must be ensured with high degrees of precision. In this paper we study an outdoor deployment of a wireless sensor network in an oi...
