Servilla: A Flexible Service Provisioning Middleware for Heterogeneous Sensor Networks

Download now Free registration required

Executive Summary

Device heterogeneity in wireless sensor networks is rendering such networks increasingly difficult to program. To address this problem, the authors present Servilla, a novel middleware that enables applications to be both platform-independent and efficient despite executing over a diverse and dynamic set of devices. It achieves this by using service-oriented computing and requiring all platform-specific functionality be encapsulated behind services, which are dynamically discovered by applications. Novel forms of service bindings and invocation semantics enable flexible yet energy-efficient in-network collaboration among heterogeneous devices. To support a wide range of devices, Servilla introduces the concept of middleware asymmetry, enabling resource-constrained devices to only provide services that can be leveraged by more powerful devices running applications.
