SUMMARY Peer‐to‐peer (P2P) overlay networks and mobile ad hoc networks share many key characteristics such as self‐organization and decentralization; they also face the crucial challenge of providing connectivity in a decentralized, dynamic environment. However, when considering ad hoc networks composed of mobile devices such as smartphones, we cannot rely on the continuous end‐to‐end path between peers as for classic Internet P2P applications; rather, we have to deal with low node density that creates mobile‐disconnected networks. Porting the P2P paradigm into mobile networks to create a mobile‐to‐mobile file sharing application will create a modern type of delay/disruption tolerant network. In this context, we discuss our new approach for P2P file sharing that considers networks composed of mobile smartphones. As an innovative feature, we leverage on peer mobility to reach data in other disconnected networks by implementing a delay/disruption tolerant network‐like store‐delegate‐and‐forward communication model, where a peer can delegate unaccomplished file download tasks to other peers. In order to increase the chances of eventually receiving the requested file while reducing the number of transmitted messages and data, social awareness is exploited by nodes to delegate unaccomplished tasks only to peers that are expected to be encountered again in the future.

“…The static connection approach employed by such systems in the wired case is not suitable for MANETs; this due to mobility disconnections are often to occur and maintenance overhead is not sustainable [9,10]. Also, in sparse mobile environments, there can be no path between the source and the destination and moreover when considering our applicative scenario, low node density could mean lower data population in the overlay which could undermine the utility of a P2P file sharing application [2,9]. For these reasons synchronous communications are not sufficient in such an environment and other communication approaches are needed.…”

“…It seems hence interesting to export a popular application such as Peer-to-Peer (P2P) file sharing into the new scenario of mobile networks. In this context, different from the classical wired P2P file sharing approach, mobile users could exchange multimedia data when in proximity of each other by establishing opportunistic, proximity-based P2P ad-hoc connections [1,2,3]. However, when dealing with mobile networks, communication cannot always rely on a continuous end-to-end path between source and destination as in the wired Internet.…”

Mobile Ad-hoc Networks (MANETs) exhibit unpredictable topology with heterogeneous node contact rates, high mobility and limited information. When dealing with such challenging environments, the mobility model has a key role in testing the performance and proving the expected behavior of routing algorithms. While synthetic mobility models have been largely used to measure quantitative aspects of routing protocols, they are not sufficient as they do not capture reliably the properties of movement in the real life scenarios. In this paper we present some experimentation done in THE_ONE simulation environment, involving our M2MShare, a peer-to-peer (P2P) delay tolerant file sharing platform for mobile networks. For testing purposes we have chosen the Working Day Movement (WDM) model which is shown to make a good approximation of human mobility patterns and provides the flexibility of configuring real life test scenarios.

“…Research trends use policies in different ways. In Ferdinando et al (2003), policies are used to control the topology growth of peer-to-peer systems. Policies are distributed to all hosts in the system with each host able to adopt only one policy at a time.…”
