Cross-Layer Designhrough an examination of the unique requirements of ad hoc and sensor networks, and we outline guidelines for cross-layer models for these networks. The next two chapters focus on existing cross-layer approaches. Chapter 8 examines proposed cross-layer architectures for ad hoc and sensor networks, w

Acoustic Underwater Sensor Networkions. One particular civilian application of interest is the deployment of underwater acoustic sensor networks. The main challenges of deploying such a network are the cost and the limited battery resources of individual sensor nodes. Thus, this case study aims at maximizing the network lifetime and

Concluding Remarks and Future Directionse 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 (

Ad Hoc and Sensor Networks: Opportunities and Challengesnetworks. Ad hoc networks could, for instance, empower medical personnel and civil servants to better coordinate their efforts during large-scale emergencies that bring infrastructure networks down, such as the September 11 attacks or the 2003 blackout in the northeast region of the United States.
