Anonymous and location-concealing routing for multihop ad hoc and sensor networks (original) (raw)
Anonymity and location privacy are two important aspects of network security for users. This thesis is concerned with location privacy and anonymity in multihop wireless ad hoc networks. More specifically, it proposes techniques to protect these features from being violated as a by-product of ad hoc routing protocols. We have proposed a novel destination-centric routing approach called Destination Controlled Routing (DCR) in which the destination is the master and controls how packets are delivered to it so that it remains unknown. In addition, DCR is designed in a way that it also preserves the location privacy and anonymity of the source node as well as the communication anonymity. Unlike other anonymous routing protocols for ad hoc networks, DCR is based on the proactive as opposed to the reactive routing approach. We have instantiated DCR for various kinds of multihop ad hoc networks. For networks of type mesh and MANET, we have proposed three variations of our V-routing protoco...
