Cross-layer interaction and service mapping (CLIASM) was designed for achieving QoS for wireless network.
P. Venkata Krishna et al., proposed a cross-layer QoS model called CLIASM for MANET.
This model proposes a back and forth flow mechanism for sharing information.
But in deploying several cross-layering approaches, one has to keep in mind the possibilities of occurrence of unintended interactions and side effects.
Conflicting interactions may create stability problems and result performance degradation.
