“…Routing techniques that rely on complex key distribution schemes or expensive cryptographic operations (for example, SMC [23]) are incompatible with HumaNets' distributed architecture and use of power-constrained devices. A significant advantage of PPBR is that it provides Privacy-Preservation using simple probabilistic techniques, and avoids the key management and computation issues present in protocols that provide more traditional cryptographic protections [6,4,21].…”

“…The disclosure of such information is particularly dangerous when HumaNets are used for covert communication in totalitarian regimes. Existing decentralized routing approaches that do not consider privacy [8,10], rely on trusted third parties [6], or assume a priori trust relationships [4] are also unsuitable for HumaNets. This paper proposes a novel routing protocol for HumaNets that protects participants' location profiles from an adversary who wishes to learn previous movements and/or determine "important" locations of network users (e.g., home, work, or the location of underground activist meetings). Our technique, which we call Probabilistic Profile-Based Routing (PPBR), balances performance and privacy by efficiently routing messages in a manner that minimizes the exposure of users' location profiles.…”

Abstract. This paper introduces a privacy-aware geographic routing protocol for Human Movement Networks (HumaNets). HumaNets are fully decentralized opportunistic and delay-tolerate networks composed of smartphone devices. Such networks allow participants to exchange messages phone-to-phone and have applications where traditional infrastructure is unavailable (e.g., during a disaster) and in totalitarian states where cellular network monitoring and censorship are employed. Our protocol leverages self-determined location profiles of smartphone operators' movements as a predictor of future locations, enabling efficient geographic routing over metropolitan-wide areas. Since these profiles contain sensitive information about participants' prior movements, our routing protocol is designed to minimize the exposure of sensitive information during a message exchange. We demonstrate via simulation over both synthetic and real-world trace data that our protocol is highly scalable, leaks little information, and balances privacy and efficiency: messages are 30% more likely to be delivered than similar random walk protocols, and the median latency is only 23-28% greater than epidemic protocols while requiring an order of magnitude fewer messages.

An innominate communication method in MANETS is categorized into proactive method, re-active method and anonymous routing method. Re-active routing is further divided into two methods, which includes superfluous traffic and routing hop-by-hop encryption. Whereas MANETs has various choices in respect to anonymous routing protocols, to provide location innominate safety to information, source node and destination node. However, a previous innominate routing protocol fully depends on station by station encryption or superfluous traffic which generates a heavy cost and offer low anonymity protection. Hence to offer a very high innominate protection, S-ALERT is pro-posed. Basic idea behind S-ALERT is to divide the whole network into number of nodes and then allocate each node a unique Id, so that we can differentiate source node and destination node. Followed by dynamic partition of network into zones and then randomly choosing nodes in zones as random forwarder, which forms a non trace-able innominate route. Along with, it also hides the source/destination node among many source/destination, in order to give very high safety to source node and destination node. It is observed that S-ALERT gives better as compared to other protocols. Hence S-ALERT protocol achieves full anonymity protection and that to at very least cost.
