Gateway and Middleware Design: Trusted WSN-TLC Network Communication and Enhanced WSN Management

In this paper the Angel Gateway is described in terms of architecture and provided functionalities, along with the design of the middleware as the core module implementing the main features of the gateway itself. The gateway, being it a fixed or a mobile one, is a key element in the Angel platform that stands between the WSN and the public network infrastructure. The role of the gateway is to enable a trusted communication between the WSN and the telecommunication operator network, besides providing advanced functionalities for the configuration and management of the WSN. A gateway middleware has been designed as a "service layer" to simplify the implementation of the applications, in order to abstract from the peculiarities of the operating system and hardware components and to provide services to manage and configure the Angel platform.
