Abstract

Tactical edge networks present extremely challenging environments for communications given their wireless ad hoc nature and the inherent node mobility. Military applications such as Blue Force Tracking, inter-team communications, remote unmanned vehicle control, and sensor data mining/fusion thus have to deal with unstable links with limited bandwidth and variable latency. The peculiar characteristics of tactical networks call for peer-to-peer approaches to realize complex, adaptive, and fault-tolerant applications to be deployed in the battlefield. This article reports on our observations from several tactical networking experiments in which we have deployed state-of-the-art applications and services that leverage P2P communications. More specifically, we discuss why P2P approaches are critical for tactical network environments and applications. We then analyze the requirements that should be satisfied by P2P middleware for tactical environments. Finally, we discuss a case study, the Agile Computing Middleware, and present experimental results that demonstrate its effectiveness.
