- 2. ABSTRACT: With the recent developments of Wireless Sensor Networks (WSNs), computing and communication have experienced huge Meanwhile, security has not received the same attention to go such developments. In this paper, we focus on the source location problem in WSNs, a hot research topic in security, and propose a probabilistic source location privacy protection scheme (PSLP) for
- 3. A more powerful adversary, which can use Hidden Markov Model (HMM) to estimate the state of the source, is considered in this study.To cope with this type of adversary, phantom nodes and fake sources, which are responsible to mimic the behavior of the source, are utilized to diversify the routing path.
- 4. Then, the weight of each node is calculated as a criteria to select the next-hop candidate. In addition, two transmission modes are designed to transmit real packets.The simulation results demonstrate that the proposed PSLP scheme improves the safety time without compromising the energy consumption.
- 5. EXISTINGSYSTEM There are many techniques, like secure routing, fake sources phantom nodes, fake cloud, and cluster, that can be applied to protect the secure location privacy.
- 6. Mayank et al. used the data mule to protect the source location privacy, data mule worked as the mobile data collection unit and collected data when the source was in its communication radius in this condition the source location privacy was changed into the protection of the mule’s moving track,
- 7. Then the authors proposed three extended versions of angle based scheme to protect the source location, however since the mule moved grid by grid the protection of the mule was not given enough attention there was still a lot of research space in reducing the time correlation.
- 8. DISADVANTAGES OF EXISTING SYSTEM Fake sources were related to the relative location of rhe source annd the sink, sensors nodes in a specific area might exhaust energy The number of converged routing paths was not clearly defined and the energy collected by nodes around the sink might be less than the energy costed by transmitting packets.
- 9. PROPOSED SYSTEM We focus on the source location privacy, which is an emerging research topic in the field of security. We propose a probabilistic source location privacy protection scheme (PSLP), which adopts phantom nodes and fake sources for the reason that these two techniques can diversify the routing path.
- 10. Two types of packets exist in the transmission, which are the real packets and the fake packets. real packets are generated by the source while fake packets are generated by fake sources
- 11. ADVANTAGES OF PROPOSED SYSTEM The proposed PSLP has exhibited a better performance than two other recent schemes in our simulations with regard to increasing the safety time while balancing the energy consumption Both phantom nodes and fake sources are integrated into the proposed PSLP, which enhance the source location privacy
