Abstract/Description:
The exponential growth of devices that rely on wireless communication to operate has introduced significant stress on the limited resources. Additionally, to offset the cost of installing new infrastructure and to maximize revenue, 5G (5th Generation) network providers are expected to extend their services beyond traditional cellular communication to support Internet-of-Things (IoT) and machine-to-machine ad hoc communication. To accommodate all these devices over the next decade, there are two key research directions that need to be adopted; (i) optimizing the use of available resources to meet the application-specific quality of service (QoS) requirements and (ii) develop technology that enables the utilization of unexplored and unlicensed parts of the spectrum to complement the current radio frequency (RF) based networks. This work focuses on how cross-layer optimized algorithms can be the answer to both these requirements for the next-generation of 5G network. First, cross-layer optimization is employed to enable both tactical and emergency ad hoc networks to meet their specific requirements. To this end, a Deadline-based cross-layer Routing and Spectrum allocation (DRS) algorithm is proposed for tactical ad hoc networks to handle the heterogeneous nature of traffic. This work also puts forth a cross-layer architecture that will enable implementation and evaluation of such cross-layer optimized routing algorithms. The proposed solution is evaluated on a software-defined radio (SDR) testbed and shown to outperform state-of-the-art routing algorithms. Next, to aid modern emergency response, a low cost Heterogeneous Efficient Low PowEr Radio (HELPER) network is designed and developed to provide complete end-to-end connectivity for both survivors and first responders. This is realized by designing an energy-aware routing algorithm that aims to maximize network lifetime. The operational feasibility of the proposed HELPER network is demonstrated by developing HELPER prototype using Commercial-Off-The-Shelf (COTS) components. Thereafter, extensive quantitative evaluation is performed on the developed HELPER testbed. Visible Light Communication (VLC) is envisioned as a major 5G technology that can be complementary to RF and help mitigate the congestion in the RF spectrum. Visible Light Ad Hoc Networks (LANET) have the potential to offer capabilities to satisfy growing industrial and military requirements, including low-latency, high bandwidth communication under high network density. The challenges imposed by hidden nodes, deafness and blockage are unique to LANET and influence the network differently from traditional Mobile Ad Hoc Networks (MANET) due to directionality and Line of Sight (LOS) requirements. Therefore, networking protocols have to be redesigned with careful consideration of these challenges. These unique challenges demand consideration of networking problems from the cross-layer perspective. As a significant step in realizing LANETs, this work first proposes an opportunistic Medium Access Control (MAC) protocol designed specifically to mitigate challenges due to deafness, hidden node problem and maximize the utilization of full-duplex communication. Next, to advance the development of LANETs, a distributed cross-layer routing protocol (VL-ROUTE) that interacts closely with the MAC layer to maximize the throughput of LANET is proposed. In this manner, a LANET with a cross-layer optimized link and network layer has been successfully designed and evaluated for bolstering the future 5G ad hoc networks.
