Wireless Sensor Networks : Applications and its Challenges

Wireless sensor networks have recently become famous because they grip the potential to change many sectors such as environment monitoring, agriculture, health, automation, and security. They have a vast potential for long term applications and also have the capacity to change human lives in different phases. Sensor nodes with wireless interface can transmit with each other to form a network. Depending on the resources limitations and used applications of WSNs security and energy management is a main reason in increasing the network lifetime. The study presents an impression of different applications of the wireless sensor networks and its Challenges.
