Wireless sensor networks

Abstract

Wireless sensor networks constitute the platform of a broad range of applications related to national security, surveillance, military, health care, and environmental monitoring. The coverage problem for Wireless Sensor Network (WSN) has been studied extensively in recent years, especially when combined with connectivity and energy efficiency. This paper focuses on the sensor replacement problem in wireless sensor networks consists of mobile sensors. Mobility equipped sensors are utilized to recover and maintain the overall coverage using the dynamic cluster concept. The proposed fault repair solution does not assume the localization information is available. Mobile sensor nodes make use of simple geometric operation to locate and replace dying nodes to recover or increase the existing coverage and connectivity.

Artificial Bee Colony Algorithm based Multi-Objective Node Placement for Wireless Sensor Network

“…The smart environment basically relies first and foremost on sensory data from the real world. The information needed by smart environments is provided by Distributed Wireless Sensor Networks (DWSN), which are Wireless sensor networks [1] are composed of a great number of sensor nodes densely deployed in a fashion that may revolutionize information collecting, which makes it a very promising technique for surveillance in military, environmental monitoring, target tracking in hostile circumstances, and traffic monitoring. The Wireless Sensor Networks (WSN) are intended for monitoring an environment.…”
