An evaluation of serverless group chat

This paper presents empirical analysis of serverless, multi-user chat in multicast-capable tactical environments. The implemented group communications middleware is based on serverless XMPP messaging. We compare the effectiveness and performance of serverless messaging over multicast, as well as typical client server TCP messaging. The experiments are performed using the Common Open Research Emulator in conjunction with the Extendable Mobile Ad-Hoc Network Emulator, to provide a higher-fidelity emulation than previous work.
