Operational Performance of the Context-Aware Broker (CAB): A Communication and Management System for Delay-Tolerant Networks (DTNs)

The Context-Aware Broker is a policy-based management system developed by the authors to achieve autonomic communication in delay-tolerant networks. This is in recognition of environment challenges when operating in remote regions, and time, human, and financial resource costs incurred during mission-specific configuration. The Context-Aware Broker seeks to limit cost overheads through achieving a standardised transmitting approach, and operating autonomically to optimise reliability and sustainability levels achieved. In achieving its network management function, a cost-benefit impact is the consequence. Performance results from the Context-Aware Broker´s deployment in ns-2.30 are presented and evaluated in this paper.
