Critical message scheduling for disaster response and recovery phases

Abstract

During disaster especially response and recovery phases, limited bandwidths and high rate of incoming messages make communication network vital resources. Allocating bandwidth to send critical messages such as well-being statuses, assistant activities etc. can determine the effectiveness of the disaster responses as messages are numerous, duplicated, and often timely critical. In this paper, we use the combination of contextual information including importance, urgency, and uniqueness to schedule messages under extreme situations. The experiments show that our scheduler can vastly out-perform traditional schedulers. This can ensure that precious information during disaster response and recovery phases are effectively handled.
