* The Chaos of Unbridled Cross-Layer Design
 
Unlike a traditional architectural design approach, where designers can focus on a single problem without worrying about the rest of the protocol stack, one must be careful to prevent unintended effects on other parts of the system. Dependency graphs are helpful for adaptation loops that occur using cross-layer design. <ref name=":02">{{Cite book|title=Cognitive Radio Communications and Networks : Principles and Practice|last=|first=|publisher=Academic Press|year=2010|isbn=9780080879321|___location=Burlington, MA|pages=201–234}}</ref> Differential algorithm systematics modified to the cross-layer interface enables rapid retrieval capabilities when the optimized protocol is defined in dynamic parameters.<ref>{{cite book |last1=Perez-Neira |first1=A |title=Cross-Layer Resource Allocation in Wireless Communications: Techniques and Models from PHY and MAC Layer Interaction |date=2010 |publisher=Academic Press |pages=72-93}}</ref> This effectively exposes the system to bypass allocation, wherein modal gates may be accessible to users for modification regardless of role-defined access level permissions.<ref>{{cite journal |last1=Xi |first1=Y |title=Distributed algorithms for spectrum allocation, power control, routing, and congestion control in wireless networks |journal=Proceedings of the 8th ACM international symposium on Mobile ad hoc networking and computing |date=2007}}</ref>
