Abstract

Present era is of Information and Communication Technology (ICT) and there are number of researchers are going on wireless Sensor Network (WSN). In Computer Science, Wireless Sensor Network is the current research field. A Wireless Sensor Network can communicate the information through wireless devices. Aim of this paper highlights WSN, its applications. It also contains various security protocols to make WSN a secure Network. With advancement in WSN, small and low cost sensor nodes become available, which have capabilities of wireless communication, sensing various types of environmental conditions and data processing. There are different types of routing protocols depending upon application and network architecture. Routing protocols provide path in the network and efficient multi-hop communication. WSNs can be found in a various applications like civilian and military worldwide which embrace enemy intrusion detection, object tracking, patient monitoring, habitat monitoring, fire detection and battlefield.
