XLAYER: A Cross-Layer Communications Substrate for Tactical Environments

摘要

The notion of a cross-layer communications substrate for tactical battlefield environments described in this work proposes to address the problem by enabling a two-way interface between higher-level applications, middleware or decision architectures, and the underlying communications infrastructure. The adaptation across multiple layers of the communication stack requires mechanisms capable of coordinating local adaptation at different time-scales to better allocate resources and capabilities in response to changes that may occur either on demand or proactively, based on explicit application requirement patterns. XLayer is a specialized crosslayer communications substrate designed to support a communications infrastructure for tactical and mobile ad hoc networks that provides the mechanisms to enable the interaction between applications and the different levels of the communications substrate to support a large range of scenarios and capabilities.
