A wireless sensor network is a wireless network consist of autonomous devices i.e.; using sensors to monitor physical or environmental conditions, like temperature, sound, vibration, pressure, motion or pollutants, at different locations.
WSNs employs multi-hop transmission mode to overcome the constraints. It operates in environments and can be subjected to side channel attacks, such as differential power analysis. In these attacks, i.e.; the adversary monitors system, repeats an equivalent operation, and takes careful measurements of power consumed during a cycle basis so as to either recover the secret key.
Terrestrial WSNs: It is capable to communicate efficient and contains thousands of wireless sensor nodes deployed in unstructured or structured manner. In an unstructured mode, i.e.; the sensor nodes are distributed within the target that dropped from a tough plane.
Underground WSNs: It contains several sensor nodes that are hidden within the ground to watch underground conditions. The sensor battery equipped with limited power difficult to recharge. In addition to this, it makes wireless communication a challenge due to the high level of signal loss.
Under Water WSNs: The networks consist of several sensor nodes and vehicles deployed underwater. Autonomous underwater vehicles are used i.e.; for gather data from sensor nodes. It involves development of underwater communication and networking techniques.
Multimedia WSNs: The networks contain low-cost sensor nodes equipped with microphones and cameras. It requires i.e.; high bandwidth for the content to be delivered easily.
Mobile WSNs: It contains a set of sensor nodes which will be moved and interacted with the physical environment. Mobile wireless sensor networks are far more versatile than static sensor networks.
