A Network Lifetime Enhancement with Secure Routing in Wireless Sensor Networks

In the wireless sensor network the protocol are desired to be designed with security in mind from scratch. Regarding the limited nature of the network nodes, the protocol design should include the efficient reserve careful method and data route security. In the incidence of stochastic errors such algorithm should produce estimate which are close sense. To identify the collusion and compromised attack based on the iterative filtering algorithm. It should be supposed to be close up to the difference of the Maximum Likelihood Estimator (MLE). Iterative filtering is done followed by bias and variance estimation. However, such assessment should be achieved with no supplying to the algorithm the variances of the sensors, engaged in practice. Proposed iterative filtering algorithm should give the reliable measures in the attendance of non-stochastic errors, such as faults and malicious attacks inside aggregating data; such algorithm should also provide an assessment of the dependability and fidelity of the data received from the sensor nodes to the optimal ones in information theoretic. This algorithm is implemented in the deployed sensor network for against the compromised attacker present in the network that can more vulnerable to the network.
