Disseminating Content through a Peer-to-Peer Infrastructure in a Disaster Zone

Nowadays, a network becomes even more essential after a disaster occurs since emergency data needs promptly delivered by community networks. Peer-to-peer approaches have considered as the candidates for content delivery mechanisms, but the provider´s outbound connections are controlled by retrievers through pull-based methods and causing only few data can be delivered because of the congested outbound traffic. This congested network is not allowed for the community network in a disaster zone since network links must be connectable as possible. Although push-based methods must be fault-tolerable to apply to community networks and increase the sender load to deliver files, utilizing push-based content delivery methods to disseminate content can reduce the usage of the connections of a file sender. Therefore, this work proposes an applicable content delivery infrastructure adopts pull- and push-based methods to deliver content through a community network in a disaster zone.
