A multihop cellular based aggregation network model was proposed

and based on network capacity region model

the capacity effectiveness of this model was analyzed. Comparison was made by both analysis and numeric simu- lation among the capacity regions and unified capacities of three network models: traditional single-hop cellular network

multihop cellular network and aggregation supported multihop cellular. Results show that the aggregation network can improve the capacity of a network even without the help of multicast and multiradio

which proves the rationality of the structure of aggregation network model.
