A Review on Various Issues and Applications in Wireless Sensor Networks

With the enormous advancement in the field of embedded computer and sensor technology, Wireless Sensor Networks (WSNs) have made remarkable impact in todays world. These WSNs consist of several thousands of sensor nodes deployed randomly, are capable of sensing, actuating, and communicating the collected information. Since wireless sensor networks are constrained by cost, scalability, topology change and power consumption, new technologies are being considered to overcome these and many other issues. This paper focuses on types of WSNs along with ways to overcome these challenges in respective WSNs and need of appropriate sensor for achieving specific application requirement. Use of efficient approach to achieve certain performance parameters has been highlighted.
