Multi-hop cellular network is a promising architecture aiming to improve the performance of current cellular network. However, there are many security challenges due to the participation of the mobile nodes in the routing process. In this paper, the authors address two challenges: route anonymity, aiming to prevent attackers from tracking a packet flow to its source or destination; and location privacy, aiming to prevent attackers from detecting the nodes' locations. Most of the existing solutions require much computational power and energy. They propose a routing protocol that provides anonymous communication by protecting the user's anonymity and location privacy.
