The combined and separated research advancement in the fields of sensing, communication, and computing have driven the research efforts in wireless sensor networks (WSN) in recent years. According to the traditional definition of WSNs, a dense, static, and prohibitively expensive sensor deployment is implicitly required, which has limited the feasibility of WSNs in non-military approaches. Aside from stationary sensor and sink deployment, the introduction of mobility of mobile terminals into WSNs can be leveraged to alleviate the burden of certain static sinks in order for efficient information repository, dissemination and sharing. In this paper, an architecture of multi-radio enabled mobile wireless sensor network (MEMOSEN) has been introduced, which has taken the heterogeneity and mobility of sensors and sinks into account. The capacity gain due to mobility in MEMOSEN have been addressed, and the design challenges and potential applications of MEMOSEN have been analyzed as well.
