Delay Tolerant Network for Disaster Information Transmission in Challenged Network Environment
After the East Japan great earthquake on March 11, 2011, many Japanese coastal resident areas were isolated from other because of destruction of information infrastructure, disconnection of communication network and excessive traffic congestion. The undelivered disaster information influenced the speed of evacuation, rescue of injured residents, and sending life-support materials to evacuation ...
متن کاملSmart Home Delay Tolerant Network for an Earthquake Disaster
In a previous paper, we proposed a rescue support system for victims buried in an earthquake disaster by constructing an ad-hoc network using home-server smart homes. However, this system has the following two problems: i) it cannot ensure sufficient density of home servers for a WLAN communication range, ii) the system does not consider areas in which home servers cannot be used such as in par...
متن کاملAutonomous Directional Anntenna Control for Delay Tolerant Networking based Disaster Information Network System in Local Areas
When there was the East Japan Great Earthquake in 2011, many areas were isolated by the high congestions and the disconnection of cellular phones or Internet. DTN (Delay Tolerant Networking) is one of effective methods for Disaster Information Network System, but the delivery rate and latency are pointed out of the problems of DTN. Besides, since there are fewer roads or pedestrians in local ar...
متن کاملOptimal Transmission and Scheduling in Delay Tolerant Network
Delay-tolerant networking (DTN) is an approach to computer network architecture that seeks to address the technical issues in heterogeneous networks that may lack continuous network connectivity. Generally in networks the ability to transport, or route, data from a source to a destination is a fundamental ability all communication networks must have. Delay and disruption-tolerant networks (DTNs...
متن کاملDelay Management in Delay Tolerant Network
In delay tolerant networks (DTN), nodes explore various opportunities to connect and communicate with each other. A series of encounters of different nodes will create such opportunities and spread a message among many nodes and eventually deliver to the designated destination. We study one common DTN scenario where the message exchanges happen when nodes meet others at certain locations. In th...
