Abstract
Recently, the development of wireless sensor networks (WSNs) is spreading rapidly. WSNs are highly distributed self-organized systems which comprise a large number of resource constrained sensor nodes. Developers of WSNs face many challenges from communication, memory, limited energy… Also, mobility has become a major concern for WSN researchers. Indeed, Mobile WSNs (MWSN) consist of mobile sensor nodes that can move on their own and also interact with the physical environment. Developing applications for MWSN is a complicated process because of the wide variety of WSN applications and low-level implementation details. Integrating context-awareness can improve MWSN applications results. In this paper, some research issues and challenges involved in the design of WSNs are presented. Model-Driven Engineering offers an effective solution to WSN application developers by hiding the details of lower layers and raising the level of abstraction. In this sense, we propose a context-aware WSN architecture and WSN metamodel to ease the work for developers in this field.

Summary
The tiny sensor nodes communicate within a short distances and collaboratively work towards fulfilling the application specific objectives of WSN’s [1]. Context-awareness has been a great deal of interest. Using conventional methods of data gathering and processing in WSNs could lead to some of the problems, so the inclusion of context-awareness in WSNs can solve the problem to a great deal. As WSNs, deal with real world environments sensor data must be delivered within time constraints so that appropriate observations can be made or actions taken. Many other functions must meet real-time constraints including: data fusion, data transmission, target and event detection and classification, query processing, and security. This research paper presents an overview of the notion of the context, WSN and MWNS and propose a context-aware WSN architecture trying to meet with real time constraints to get better results for WSN applications.
