Description: Mobile wireless sensor networks (MWSNs) have recently launched a growing popular class of WSN in which mobility plays a key
role in the execution of the application. In recent years, mobility has become an important area of research for the WSN community. The
increasing capabilities and the decreasing costs of mobile sensors make mobile sensor networks possible and practical. Although WSN deployments
were never envisioned to be fully static, mobility was initially regarded as having several challenges that needed to be overcome,
including connectivity, coverage, and energy consumption, among others.However, recent studies have been showing mobility in a more
favorable light. In this article, an overview of proposals that evaluate mobile communication in WSNs is presented. Platform: |

Communication between health care providers and consumers is a critical part of effective health care delivery. Yet, the strategic use of interpersonal communication in health care delivery is most complex, multifaceted, and often problematic, necessitating careful study of the communication process in health care to increase understanding and help improve health communication practices. The National Cancer Institute (NCI) sponsored an expert symposium on consumer/provider communication research to examine progress and identify gaps in the research literature on doctor/patient communication. This paper and this special issue of Patient Education and Counseling reviews several of the key perspectives and suggestions presented at the symposium for directing future research and applications concerning consumer/provider communication.)
