Many security protocols have been developed to provide privacy in sensor networks. Security risk in sensor networks is one of the significant issues to be dealt with. The existing techniques guard the data only against the local eavesdropper who is having limited knowledge of the network topology. A stronger adversary such as global eavesdropper can still analyze the pattern of traffic and launch advanced attacks such as flow tracing and traffic analysis. Due to these advanced attacks the privacy of the users is compromised.
