Enhance Wireless Network Performance and Security with Reconfigurable Antennas
Abstract
Providing higher throughput, lower latency, and ubiquitous connectivity network services have attracted significant attention in recent years. However, this technology has some inherent limitations that pose significant reliability, throughput, and security challenges to researchers. For example, designing high performance multi-hop wireless networks (MWNs) has remained challenging due to unreliable wireless links, the interference among wireless links, etc. Most existing solutions address these challenges from various layers (e.g., power control, opportunistic routing, and network coding). However, none of them can alter the fundamental characteristics of the physical wireless channel itself, which leads to limited performance gains. Reconfigurable antennas (RAs) have emerged as a disruptive antenna technology that offers a promising alternative to solve the above challenges at the PHY-layer. RAs can agilely switch among many different antenna states including radiation patterns, so as to suppress interference and maintain high connectivity at the same time. However, so far, the potential of RAs to enhance performance in multi-hop wireless networks has not been explored. Moreover, the state diversity of RAs can be used to enhance PHY-layer security by proactively and dynamically randomizing the physical channel, to create an artificial advantage against the adversary. However, there is a lack of systematic modeling of attackers behaviors for some strong but practical attacks, and no quantitative security guarantee can be provided.
