This research proposal is dedicated on the study of M2M communications theory and its implementation methods under the environment of heterogenous wireless networks（HWNs）. To pursue a more uniform standard of M2M communications and to improve its technical compatibility, we will try to solve the following scientific problems. The first is intelligentized networking for non-IT machine-to-machine communications; The second is collaborative convergence and resource share of HWNs; and the third is how to achieve a flexible load bearing and tenacious connection to diverse M2M service. The main tasks will cover: system architecture of HWNs for ubiquitous M2M communications; flexible M2M transmission methods under the environment of HWNs; tenacious connection strategies for the diverse requirement of M2M applications; advanced M2M communication demo platform under HWNs. The creative contribution of this project may be: presenting a multi-domain, multi-plane and multi-layer defined network architecture of ubiquitous M2M communications based on various entitative network with sufficient share of resource and service; proposing adaptive schemes between different service requirement and networking capability for flexible M2M communications; the methods of delay tolerance M2M communications with user experience improvement; the methods of M2M tenacious connection under HWNs.
