The recent emerging fields in data processing and manipulation has facilitated the need for synthetic data generation. This is also valid for mobility encounter dataset generation. Synthetic data generation might be useful to run research-based simulations and also create mobility encounter models. Our approach in this paper is to generate a larger dataset by using a given dataset which includes the clusters of people. Based on the cluster information, we created a framework. Using this framework, we can generate a similar dataset that is statistically similar to the input dataset. We have compared the statistical results of our approach with the real dataset and an encounter mobility model generation technique in the literature. The results showed that the created datasets have similar statistical structure with the given dataset.

“…The nodes have the capability to store incoming routing messages in the buffer. When the routing message is exchanged between two or more nodes in the transmission range of each other, the nodes deliver them to the other relay nodes toward destination node [8], [18], [25]. In the mobile ad-hoc network, to deliver data from a source node to a destination node, firstly the setup phase is performed to determine a path from the source node to the destination node.…”

Abstract:Recently, Delay Tolerant Networks (DTNs) have been intensively researched to overcome unstable communication due to the intermittent link connection in wireless communications. In wireless DTNs, to enable continuous connectivity, data are exchanged through intermediate nodes in the path toward the destination node by store-andforward approach. However, since the participating nodes in the network are not fully trusted, a secure data exchange mechanism in the DTNs would be strongly desirable. In this paper, we propose a secure data exchange system in the wireless DTNs using Attribute-Based Encryption (ABE) to provide two properties: (i) content data can be accessed by only authorized nodes that are dynamically defined by a policy on the attributes while keeping its integrity from alteration during transmission, and (ii) routing messages are encrypted and authenticated such that only the attributebased authorized nodes can exchange the routing messages, where multi-hop routing messages are encrypted and authenticated by the ABE. Our experimental results show the practicality of our system.

In Delay-Tolerant Networks (DTNs), nodes forward data opportunistically upon contact because of irregular connectivity and low network-denseness. In this type of networks, energy plays an important role in successful data delivery and enhancement of network lifetime. To address the problem of selecting appropriate relay nodes for data forwarding, recently researchers are using concepts of social networks in the design of DTN routing schemes. This is because of its ability to make forwarding decisions based on the knowledge of long-term and more stable social characteristics of the nodes. In this paper, we propose an energy-aware relay selection scheme to support multiple multicast sessions based on an existing social-based single-data multicast scheme. The proposed scheme selects relays for delivering data to the destinations based on the centrality, one of the important social network characteristics, as well as on the residual energy of the DTN nodes. Our proposed scheme is shown to have polynomial-time complexity. We claim that our scheme supports higher number of multicast sessions thereby maintaining longer lifetime of the network while achieving required data delivery ratio compared to a prominent single-data multicast scheme. Our claim is validated through quantitative performance analysis.
