Constraint Design and Modelling of Multi-Hop Multi-Band Wireless MIMO Networks

Recent technological advances have enabled SDRs to switch from one frequency band to another at minimum cost, thereby making dynamic multi-band access and sharing possible. On the other hand, recent advances in signal processing combined with those in antenna technology provide MIMO capabilities, thereby creating opportunities for enhancing the throughput of wireless networks. Both SDRs and MIMO together enable next-generation wireless networks, such as mesh networks, to support dynamic and adaptive bandwidth sharing along time, frequency, and space. In this paper, we design and model the radio and interference constraints on multi-hop wireless networks when they are both SDR-capable and MIMO-equipped. The developed constraint models can be used for a variety of networking applications, such as network performance evaluation, routing algorithms, and admission control and QoS mechanisms.
