A Routing Method for Time-constrained File Transfer in Wireless Mesh Networks

摘要

In recent years, the number of requests to transfer files through networks are increasing, and the file capacities is also getting larger. These requests are generally processed with the best effort, and depending on the network situation. On the other hand, a model is considered when a file transfer is completed by a specified deadline, and a request that cannot be completed by the deadline is rejected. Wireless mesh networks are expected to be a system that can provide disaster information without depending on communication infrastructure during a disaster. When using wireless networks, however, the communication environment becomes unstable compared with wired networks and more requests will be rejected. In order to reduce the number of rejected requests, it is important to find more efficient routes. In this paper, we propose a routing method for such a time- constrained file transfer in wireless mesh networks.
