Adaptive information dissemination: An extended wireless data broadcasting scheme with loan-based feedback control

The dissemination of numerous information broadcast services gives rise to the scalability issue in wireless networks.
Previous researchers have shown that the push-based data broadcast mechanism is efficient in reducing message traffic. However,
most research efforts are dedicated to the dissemination of static information contents. In practice, information broadcast services can
produce and deliver dynamic information contents. To efficiently convey the dynamic data, we devise, in this paper, an adaptive
information dissemination mechanism by exploiting the functionality of data broadcasting, to support the dissemination of static and
dynamic information services simultaneously. In our design, both static and dynamic information services are subsumed as service
groups, i.e., the building blocks with the uniform representation of structure and group popularity and, thus, the conventional scenario
becomes a special case of our framework. Furthermore, in order to tolerate the broadcast traffic dynamics, we design an online loanbased
slot allocation and feedback control technique to deal with the adaptation of the service group classification, bandwidth
allocation, and broadcast schedule so as to avoid performance degradation. It is shown by the experimental study that the proposed
adaptive information dissemination mechanism associated with the online loan-based feedback control is able to achieve a substantial
reduction of message traffic for dynamic information dissemination in wireless networks.
