Trace Based Analysis On Mobile Social Networks (MSNETS)

The context of intermittently connected networks, DTNs, Pocket Switched Networks (PSNs), and Opportunistic Networks, a number of routing schemes have been proposed for data forwarding and content dissemination. These routing schemes exploit the fact that end-toend paths do exist over time in intermittently connected networks, which depend on a store-carry-and-forward pattern. Most recent work focuses on proposing routing schemes to achieve comparable performance as Epidemic routing, but with a lower cost measured by the number of relays needed for forwarding. Spray&wait and its extended scheme Spray&focus both select a fixed number of data relays, while some other schemes make relay selection decisions based on the nodes’ data forwarding metrics. In a relay forwards data to another node, whose forwarding metric is higher than itself. Delegation forwarding is a singlecopy forwarding scheme, which reduces the cost, by only forwarding data to the node with the highest metric. These schemes use the intrinsic mobility of the nodes in the network. Another set of work considers the possibility of controlled mobility for network routing. They have proposed communication models where special mobile nodes (Message Ferry and Data MULEs.) facilitate the network connectivity. These models always assume the special nodes move with fixed routes. SCFR studies a multipleferry scenario, and the ferry trajectory is adaptive to the actual traffic and location of destinations. Moreover, multiple relays are allowed in SCFR, but with control. However, only ferries are mobile and all other nodes are static. Designing a customized ferry route without disturbing nodes’ movements in mobile DTNs. They laid many constraints on node mobility, and did not consider the social nature of the network. On the contrary, our data dissemination scheme exploits the social characteristics of mobile networks without any online collaboration between the superuser and regular users in the network.
