Abstract

Opportunistic spectrum access aims to exploit the instantaneous spectrum availability using sophisticated signal processing and networking techniques. Cognitive MAC that enables instantaneous detection and efficient utilization of spectrum opportunities is one of the key components of opportunistic spectrum access. In this paper, we pursue a cross-layer approach that integrates opportunity assessment and opportunity allocation for optimal spectrum utilization. We develop optimal cognitive MAC protocols for multihop ad hoc networks

面向频谱敏捷性的认知MAC跨层方法

机会频谱接入旨在利用复杂的信号处理和网络技术开发瞬时频谱可用性。认知MAC能够实现瞬时检测和有效利用频谱机会，是机会频谱接入的关键组成部分之一。在本文中，我们追求一种跨层方法，将机会评估和机会分配相结合，以实现最佳频谱利用。我们为多跳自组织网络开发了最佳的认知MAC协议
