Shifting to Dynamic WSN Paradigms
Sharief Oteafy, Hossam S. Hassanein · 2014
A movement began in wireless sensor network (WSN) literature, demanding a more dynamic approach to the design and implementation of sensor nodes (SNs). WSN middleware generally entails an efficient and dynamic interface between nodal services at the application layer to underlying operating system functionalities. Dynamic reprogramming is aimed at changing the software running these nodes. The mass of literature on services in wireless and wired networks, with major advancements in telecommunications and web services, steered a considerable amount of attention toward approaching WSNs as a group of service enablers. Thus, having a predefined set of protocols that enable service discovery, authentication and usage charging, these protocols could be adopted in a WSN setting to sustain a given application(s). A new paradigm of sensing has emerged in a domain called crowd or public sensing. It builds upon research in mobile computing and WSNs.
