A Review of Wireless Sensor Network from Future Perspective

Abstract

WSNs have unique characteristics such as low-cost deployment, flexibility, scalability, low-power consumption, and robustness, which makes them well suited for a wide range of applications in different domains. Wireless Sensor Networks (WSN) are at the start of their evolution and have yet to overcome many research difficulties.WSN must still be able to operate on limited power and in remote or challenging
environmental conditions, face issues of scalability and reliability, and have to be able to interpret complex data. Furthermore, the way information is processed, shared and used by the network is still being researched, as well as how to best use and organise the sensors that make up the system. In addition, security and privacy are important considerations and methods of constructing secure WSNs are being developed. Many of these research challenges are still being addressed and new ones appear as WSN make their way into different applications.
