Data transmission over wireless networks is challenging due to the occurrence of burst errors, and packet loss caused by such errors seriously limits the maximum achievable throughput of wireless networks. To tailor efficient transmission schemes, it is essential to develop a wireless error model that can provide insight into the behavior of wireless transmissions. In this study, we investigate the...
In conventional networks, such as the Internet, it is assumed that there exists a fully connected path between any pair of nodes at any time. In delay tolerant networks (DTN), however, the connected path may be broken, and nodes may be partitioned into two disconnected subsets because of the movement or failure of some nodes. Thus, the data transmission requirements can not be satisfied by traditional...
In this paper, we address the challenges of content transfer in opportunistic networks, and propose techniques to better facilitate data dissemination based on the characteristics of the content. To investigate this problem from its origins, we propose three message scheduling algorithms: Sequential Forwarding (SF), Full Interleaving (FI), and Block-based Interleaving (BI). Each algorithm is embedded...
