Today we learned of a new project advancing day by day and improve much communication against network outages, for example, natural disasters. If an earthquake happens tomorrow in Spain (knock on wood) and is carried forward telecom infrastructure major carriers, all (or almost all) we would run red . We would be “cut off” in front of a natural disaster in which the key element is the communication with the authorities and information instantly. Well, some great minds have been thinking about how to solve this problem and it seems to be pretty close to a solution very feasible .Thomas and Jeff Robble, Mitre workers, wanted to find a solution to the problem posed in this entry. This would create a connection security by WiFi chips for our Android smartphones. Although still a prototype, is a project very interesting to watch. The SPAN project (Smart Phone Ad-Hoc Networks) reconfigures WiFi chips of our phones and routers becomes so that others who are close to also do the same and, when connected together, form a large mesh network AdHoc. Then, these terminals can communicate with other creating a large national or regional network. The SPAN intercepts all communications by Global Handset Proxy , so the VoIP type applications, twitter, email, etc.., Function normally.
This has been achieved by merging and compiling the kernel source code of Android and the Wireless Extension API for Linux. It is, in short, a working framework on research to improve the connection between these networks (the AdHoc). SPAN enrrutamiento module is designed to be plug & play so it can be easily replaced. Researchers and developers who are interested in experimenting with new routing protocols like this, must squeeze hours and hours to build an entire application using the framework of SPAN.The current version works alternating protocols olsrd and Dijkstra to test for differences in the performance of the network. The initial tests are promising and have shown that each device on the network can operate at about 30 meters away from your “neighbor” closer. The initial tests with 30 nodes not reached the limit of channels supported by protocol 802.11 . SPAN already have the source code posted on GitHub to promote their development. It also has an application target=”_blank”> for those who want to live experience. The GitHub repository original and has resulted in about 500 secondary projects . Almost anything …
Certainly, SPAN is a project that, to reach fruition, save more than one life . With a sufficient number of nodes, we would need towers to enjoy our mobile network.path: Network World
