Wireless sensor networks (WSNs) refer to networks of spatially dispersed and dedicated sensors that monitor and record the physical conditions of the environment and forward the collected data to a central location. WSNs can measure environmental conditions such as temperature, sound, pollution levels, humidity and wind.
Sensor Media Access Control(S-MAC) is a network protocol for sensor networks. Sensor networks consist of tiny, wirelessly communicating computers (sensor nodes), which are deployed in large numbers in an area to network independently and as long as monitor their surroundings in group work with sensors, to their energy reserves are depleted.
Basically a key predistribution scheme has 3 phases: Key distribution; Shared key discovery; Path-key establishment; During these phases, secret keys are generated, placed in sensor nodes, and each sensor node searches the area in its communication range to find another node to communicate. A secure link is established when two nodes discover ...
Security as a service : These security services often include authentication, anti-virus, anti-malware/spyware, intrusion detection, penetration testing and security event management, among others. In practice many products in this area will have a mix of these functions, so there will often be some overlap – and many commercial vendors also ...
An example of a physical security measure: a metal lock on the back of a personal computer to prevent hardware tampering. Computer security (also cybersecurity, digital security, or information technology (IT) security) is the protection of computer software, systems and networks from threats that can lead to unauthorized information disclosure, theft or damage to hardware, software, or data ...

A virtual sensor network (VSN) in computing and telecommunications is an emerging form of collaborative wireless sensor networks. [1] In contrast to early wireless sensor networks that were dedicated to a specific application (e.g., target tracking), VSNs enable multi-purpose, collaborative, and resource efficient WSNs.
