High Energy And Spectral Efficiency Analysis For Cognitive Radio Ad-Hoc Network Based Spectrum Aggregation

Cooperative routing and spectrum aggregation are two promising techniques for Cognitive Radio Ad-hoc Networks (CRAHNs). In this paper, we propose a spectrum aggregation based cooperative routing protocol, termed as SACRP, for CRAHNs. This is the first contribution on spectrum aggregation-based cooperative routing for CRAHNs. The essential target of SACRP is to provide higher energy efficiency, improve throughput, and reduce network delay for CRAHNs. In this regard, we design the MAC and physical layer, and proposed different spectrum aggregation algorithms for cognitive radio (CR) users. We propose two different classes of routing protocols; class A for achieving higher energy efficiency and throughput, and class B for reducing end-to-end latency. Performance evaluation demonstrates the effectiveness of SACRP in terms of energy efficiency, throughput, and end-
