New adaptive mobility model should be integrated with data aggregation approach. In addition, these both units should be part of new middle layer that should support MAC and Network layer. Second part of your question is regarding QoS provision. Ofcourse it is possible to maintain QoS paramters incorporating the features of  detecting the node postion, distance and packet generation rate in middle layer (adpative layer)

Data aggregation Data centric routing using information from phhyisical layer has been observed to improve energy efficiency, also quite a lot of work has been done on applying cross layering from retransmittion percpective as MAC and IP and Physical layer each would do it time to time.

I suggest the following reading list.

Link Quality estimation support from PHY layer can be utilized at MAC layer to improve the quality of service.   Additionally, the  MAC  protocol available for wireless technologies support number of modes of operation, but do not exactly provide any mechanism how and when to switch between these mechanism.  One can look how the some information which is available at other layer can be used to switch between different mode of operations of a MAC. For example, congestion detection at network layer of transport layer can be utilized to improve the performance of MAC.
