Concluding Remarks and Future Directions

Abstract

This book focuses on cross-layer design for ad hoc and sensor networks. The first part of the book surveys layered approaches for these networks, while the second part of the book discusses explicit cross-layer design. Part III of the book takes Jurdak’s cross-layer optimization framework as an example that is applicable to three diverse case studies. The case studies cover both ad hoc and sensor networks with diverse communication technologies (RF, UWB, and acoustics) and with diverse application requirements, including energy efficiency, network longevity, throughput maximization, fair access, and low latency. The applicability of Jurdak’s framework to the diverse case studies highlights the success of synergistic approaches that provide flexibility for multiple scenarios on one hand and efficient performance for each scenario on the other.
