Cognitive Jointly Optimal Code-Division Channelization and Routing Over Cooperative Links

Abstract

We developed a new spread-spectrum management paradigm in which, unlike mainstream dynamic spectrum access research, digital waveforms are (i) designed to occupy the entire available spectrum and (ii) adaptively track the interference profile at the receiver to maximize link capacity while avoiding interference to existing users. In this context, we studied the problem of maximizing the network throughput of a multi-hop network through joint routing and spread-spectrum channelization. We first presented a centralized formulation of the network control problem. We then developed an algorithm that can be seen as a distributed localized approximation of the throughput-maximizing policy. We refer to the proposed jointly-designed routing and code-division channelization algorithm as ROCH (Routing and cOde-division CHannelization).
