In this paper, an investigation toward mobile P2P architecture brings a new insight to realize future mobile cloud computing systems. Although mobile devices capacity in storing data and running computational process is very limited, the main problem for implementing mobile cloud computing environment is still motivated by the classic issue of information properties query process. Heterogeneous wireless networks (HWNs) architecture then exploited to solve this fundamental problem. The HWNs information properties dispersion model based on coverage area of mobile node aid to simplify the querying process. By HWN and mobile P2P integration a reliable mobile cloud computing service can perform services and resources exchange among peer nodes. In addition this integrated architecture gives the extension of mobile P2P into Network as a Service (NaaS) approach to resource sharing among mobile users.
