Abstract
The widespread availability of miniature wireless devices such as cell phones, laptops, mobiles has become an indispensable part of our life. The increase in the number of smart phone users has lead to the increase in the peer-to-peer adhoc content sharing. Traditional data delivery schemes are not suitable for such networks due to intermittent connectivity between smart phones. In Delay Tolerant Networks (DTNs) the core challenge is to cope with lack of persistent connectivity and yet be able to deliver messages from source to destination. In particular, routing schemes that leverage relays’ memory and mobility are a customary solution in order to improve message delivery delay. To share the contents in such a scenario, researchers have proposed store-carry-forward as an efficient content sharing scheme where a node stores a message and carries it for certain duration until a communication opportunity arises and then delivers it to the destination. Previous works in this field focused on whether two nodes would encounter each other and the place and time of encounter and did not consider the activities of malicious peers. This paper proposes discoverpredict-deliver as efficient content sharing scheme that enable peers to share contents and also presents distributed algorithms that enable a peer to reason about trustworthiness of other peers based on past interactions and recommendations .We scheduling the large file into small packets and delivering through multipath to destination, for this we use optimal user centric allocation and scheduling the packets in the receiver side.
