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.
