A Novel Approach To Avoid Intrusion In Area Monitoring

WSN had become the most popular choice for area monitoring. Many types of sensor nodes are available for monitoring the area like seismic sensors, image sensor, thermal sensor etc. WSN is the most economical method for area monitoring due to which the technique has been adopted by different countries. Use of sensors for this purpose had reduced the cost of monitoring. Thus, security factor has been compromised to some extent. Now, the intruder can easily sense the information being transmitted about an area and he can change it also very easily. Therefore, the paper provides a preventive mechanism against this man-in-the-middle attack so that this confidential information about an area should reach the concerned officials safely and we would be able to prevent the area from accidents.
