Electricity consumption in the world is constantly increasing, making our lives become more and more dependent on electricity. There are several new paradigms proposed in the field of power grids. In Japan, especially after the Great East Japan Earthquake in March 2011, the new power grid paradigms are expected to be more resilient to survive several difficulties during disasters.

Recently, wireless body area networks (WBANs) have attracted significant consideration in ubiquitous healthcare. A number of medium access control (MAC) protocols, primarily derived from the superframe structure of the IEEE 802.15.4, have been proposed in literature. These MAC protocols aim to provide quality of service (QoS) by prioritizing different traffic types in WBANs. A contention access...

This paper proposed PBMA (Priority Based Multiple Access) and PBMA-TC (Priority Based Multiple Access with Throughput Control) for mobile communication to meet user’s demands. We define the priority according to the waiting time, which includes request access time and waiting time at Request Table. We assumed two grades of priority, high priority and low priority. The former is corresponds to t...
