摘要：Wireless Sensor Networks (WSNs) use tiny, inexpensive sensor nodes with several distinguishing characteristics: they have very low processing power and radio ranges, permit very low energy consumption and perform limited and specific monitoring and sensing functions. Several such wireless sensors in a region self-organize and form a WSN. Information based on sensed data can be used in agriculture and livestock, assisted driving or even in providing security at home or in public places. A key requirement from both the technological and commercial point of view is to provide adequate security capabilities. Fulfilling privacy and security requirements in an appropriate architecture for WSNs offering pervasive services is essential for user acceptance. Five key features need to be considered when developing WSN solutions: scalability, security, reliability, self-healing and robustness. In this system, we have used a technique called Linear Feedback Shift Register (LFSR) to increase the security and to detect and correct the errors in received signal. It also includes the comparison of AES, a cryptogarhiy technique used for security and LSFR for error detection and correction and at the next level, experiment has been done by using LSFR for both, for security measure as well for error correction.ta
