communication protocol messaging system XML message filtering hybrid architecture binary XML

To overcome limited network bandwidth conditions which occur frequently in tactical networking environments, an integrated solution that includes architecture, a message format, and a messaging scheme is needed. In this paper, we propose a publish-subscribe based hybrid messaging system architecture and a novel messaging model with an XML element level filtering scheme and data representation to overcome limited networking conditions in tactical environments. Herein, we present the prototype messaging system based on our proposed hybrid architecture. Evaluations of our proposed scheme were conducted to prove its effectiveness. The empirical experimental results showed that our scheme enhanced the message size performance by an average of 34% compared to conventional XML and message encoding performance was also enhanced an average of 7.1 times compared to EXI. The prototype system achieved a 21.7-fold maximum improvement in filtering performance processing time.
