Middleware: Middleware challenges and approaches for wireless sensor networks

The use of a novel approach, middleware layer, to fully meet the design and implementation challenges of wireless sensor network technologies is discussed. It is suggested that a complete middleware solution should contain a runtime environment that supports and coordinates multiple applications to achieve adaptive and efficient system resources use to prolong the life of the sensor network. The design and development of a successful middleware layer must address many challenges such as managing limited power and resources, scalability, heterogeneity, real-world integration, and quality of service. Middleware using autonomic computing could provide more robustness, reliability, and self-management.
