Wireless Sensor Networks (WSNs) location privacy protection is an important issue. In this paper, the authors address the necessity of concurrently protecting the location privacy of both the source and sink. They propose Dream Protocol to deliver messages from source to sink, which can protect the end-to-end location privacy against the local eavesdropper. They also implemented this scheme on the NS-2 platform and evaluate the performance in terms of end-to-end latency and energy consumption. The results illustrate that their proposed privacy protection schemes can obtain satisfied performance.
