Mobile Computing Middleware

摘要: Recent advances in wireless networking technologies and the growing success of mobile computing devices, such as laptop computers, third generation phones, personal digital assistants, watches like, are enabling new classes applications that present challenging problems to designers. Mobile devices face temporary loss network connectivity when they move; likely have scarce resources, low battery power, slow CPU speed little memory; required react frequent unannounced changes environment, high variability bandwidth, resources availability. To support designers building applications, research field middleware systems has proliferated. Middleware aims at facilitating communication coordination distributed components, concealing complexity raised by mobility from application engineers much possible. In this survey, we examine characteristics distinguish them their fixed counterpart. We introduce a framework categorisation various designed mobility, detailed comparative review major results reached field. An analysis current trends inside community discussion further directions conclude survey.
