Wireless Access Networks, such as Wi-Fi, have been widely deployed due to their convenience, portability, and low cost. However, they still suffer inherent shortcomings such as limited radio coverage, poor system reliability, and lack of security and privacy. Privacy threat is one of the critical issues in Multi hop Wireless Networks, where attacks such as traffic analysis and flow tracing can be easily launched by a malicious adversary due to the open wireless medium. Network coding has the potential to thwart these attacks since the coding/mixing operation is encouraged at intermediate nodes. In this paper, we are giving the privacy and security in Multi hop Wireless Networks using Network Codings with the help of traffic analysis. We have shown the event reporting in wireless sensor networks, where flow tracing can help attackers to identify the location of concerned events, E.g., the appearance of an endangered animal in a monitored area, and then take subsequent actions to capture or kill the animals.
