Abstract

How to exchange information between parties in a disaster management system is one of the fundamental challenges to support timely and efficient disaster response and relief. Specifically, the timeliness, scalability, and availability are three desirable features for information exchange. We call the framework to support information exchange with the three features an Open Information Gateway (OIGY). In this paper, we present the challenges of information gateway and the design of the communication protocols and landmark-based service recovery mechanism to support the aforementioned features. The mechanism aims at recovering the real-time publish and subscription services within an affected region. The developed method allows a landmark service node to monitor pub/sub service within a region, rather than the entire pub/sub network. To evaluate the performance of the service-recover mechanism, we measured its transmission and recovery overhead under different number of message brokers in the network. Keywords: middleware, message publish and subscription, service recovery.
