Abstract.
The conventional layered protocol architecture does not provide optimal performance for wireless mesh networks (WMNs). Optimization decomposition of protocol stack can achieve optimal network performance. This methodology usually results in a clean-slate protocol architecture that is different from the protocol architecture of WMNs. Such a difference actually proves the need of cross-layer design. Specific features pertained by WMNs also illustrate the need of cross-layer optimization across different protocol layers. In this talk motivations of cross-layer design in WMNs are explained. Moreover, cross-layer optimization schemes and algorithms between different protocol layers are investigated with an objective of shedding light on open research problems and new approaches. Guidelines for carrying out cross-layer design in WMNs are also provided.
