Packet routing is important for Vehicular Delay Tolerant Networks (VDTNs).Opportunistic routing algorithms based on historical records are insuciently accurate in forwarder selection due to movement randomness of vehicles. Trajectory-based routing algo- rithms tackle vehicle movement randomness but cannot be directly used in VDTNs due to the dependence on APs. In this paper, we develop a distributed...
In this paper, we focus on the multi-copy routing in Vehicle Delay Tolerant Networks (VDTNs). In current multi-copy routing, the different copies of each packet search the destination node independently, which leads to a low utilization of copies since they may search through the same path repeatedly without cooperation. To solve this problem, we propose a fractal Social community based efficient...
The search way of traditional search engines is the full-text retrieval based on inverted index, which is also the retrieval way used to query the index database based on the search statement, and this doesn't make good use of the meaning expressed by the search statements, thereby failing to accurately identify the specific demand of users, and this is bound to give users greater search costs. The...
We have employed the Linux on-demand read-ahead framework in our campus wide storage service system call MeePo. The appropriate read-ahead mechanism can significantly increase IO throughput and improve user experiences by hiding network latency which is critical for real-time applications. Our strategy is based on the data accessing characteristic of MeePo system. The read-ahead framework uses the...
