Mobile wireless sensor networks (MWSN) is a subdomain of wireless sensor networks in which sensors and/or sinks are mobile. In this study, we propose a scheme for providing trajectory privacy of mobile sink nodes. The proposed scheme is based on random distribution of data packets. Moreover, sensor nodes do not use location information of the mobile sink or its trajectory. We performed simulation based and analytical performance evaluations for the proposed scheme. The results show that a network with up to 99% data delivery rate can be obtained by appropriate configuration while maintaining a fair level of trajectory privacy of the mobile sink node.
