摘要: Wireless sensor networks (WSNs) have emerged as an effective solution for a wide range of applications. Most the traditional WSN architectures consist static nodes which are densely deployed over sensing area. Recently, several based on mobile elements (MEs) been proposed. them exploit mobility to address problem data collection in WSNs. In this article we first define WSNs with MEs and provide comprehensive taxonomy their architectures, role MEs. Then present overview process such scenario, identify corresponding issues challenges. On basis these issues, extensive survey related literature. Finally, compare underlying approaches solutions, hints open problems future research directions.
