Wireless sensor networks are widely used in our daily life. It consists of various sensors which collect different information containing the identity, status, and location of an object or any other business, social or privately relevant information. But we pay attention to some issues related to sensor’s location privacy. A user would issue a query and expect a response to be returned within the deadline. While the use of fault tolerance mechanisms through redundancy improves query reliability. The system develop a mathematical model for the lifetime of the sensor system as a function of system parameters including the “source” and “path” redundancy levels utilized. Data sensing and retrieval in wireless sensor systems have a widespread application in areas such as security and surveillance monitoring. Redundancy management of clustered heterogeneous wireless sensor networks utilizing multipath routing to answer user queries. Which the lifetime of a heterogeneous wireless sensor network is maximized while satisfying the reliability. We applied our analysis results to the design of a dynamic redundancy management. The best design parameter settings at runtime in response to environment changes to prolong the system lifetime. In the existing system, the system do not take effort to ensure that all generated aggregate locations satisfy this condition. In this project the system proposed a Reciprocal protocol for generating k-anonymized Aggregate Locations (REAL for short hereafter) in WSNs. REAL is energy-efficient, which is essential for prolonging the lifetime of WSNs. Then the system design a heuristic in-network algorithm that guarantees the reciprocity property and attempts to generate aggregate location areas as small as possible.
