Aim: The Aim of this Research paper is analyzing the security over the Firmware attacks in Wireless Sensor Network by using the Novel Centralized Algorithm and Adaptive Routing algorithm classification Algorithms. Materials and Methods: The study contains the survey among the Different operating systems such as FreeRTOS, POSIX or WIN32. There are nearly 10 simulators to take a survey among. Here the number of groups is 2 and group1 is Centralized algorithm (87.67%) and group2 is Adaptive Routing (81.25%) and the sample output size is 32. Result: The performance has been improved in terms of accuracy for the novel Centralized Algorithm with 87.67% while the Adaptive Routing Algorithm has shown accuracy of 81.25%. The mean 87.67, mean accuracy detection is ±1SD and significant value is 0.593 (p > 0.05) from an independent sample T test. Conclusion: The final outcome of the centralized algorithm is found to be more significantly more accurate than the Adaptive routing algorithm.
