Sensor technologies are vital today in gathering information about certain environments and Wireless Sensors Networks (WSNs) are getting more widespread use every day. The recent advances in Wireless Sensor Networks open new scenarios where sensors can be rapidly deployed without any existing infrastructure. Such networks are useful in many fields, such as smart grid, smart water networks, intelligent transportation, smart homes, health monitoring, environmental control, military applications, etc. Ensuring energy efficient and reliable transport of data in resource constrained WSNs is one of the primary concerns to achieve a high degree of efficiency in monitoring and control systems. In WSN, reliable monitoring of a phenomenon depends on the collective data provided by the target cluster of sensors and not on any individual node, There are several strategies to reduce the power consumption of WSN nodes by increasing the network lifetime and increase the reliability of the network by improving the WSN Quality of Service. However, there is an inherent conflict between power consumption and reliability. This paper describes the concept of WSNs which has been made viable by the convergence of microelectronics systems technology and wireless communications. |
