Security challenges of wireless sensors devices (MOTES)

The excess in the use of a technology always opens new challenges for its implementers due to the security issues they start facing, and thus the role of the researchers begins. The increase in the trend of Wireless Sensor Networks (WSNs) usage has given birth to many security threats. Many research firms, universities have pitched in to this area of research and as a result many Wireless Network Architectures came into life. At early stages, the researchers were more focused on the securing the WSNs without considering the optimization factor. As a result, such architectures involved heavy computation which slowed down the process and also faced hardware limitations. The focus of the current generation research work on WSN is providing “secure and optimal” solution. This has proved to be very challenging, but the efforts have been continuously going on in this area due to which this industry is booming. Focused in this paper is on the analysis of the research work done on the WSNs security, their current status of reliability, some recommendations for a safer WSNs environment, and the future research work required in this area.
