Evaluating Implementations of Service Oriented Architecture for Sensor Network via Simulation

摘要

With the use of Service Oriented Architectures in areas such as sensor network it becomes increasingly necessary to be able simulate the interactions of such a system before actually implementing it. This work explores the viability of two different implementations of a simulation of service composition in dynamic sensor networks. The first simulation is written in C++ with a graphical user interface using Qt and visualizations supplied via Graphviz. This simulation supports distributed and centralized composition with a type hierarchy and multiple-service statically-located nodes in a 2- dimensional space. The second simulation uses the actor model programming language SALSA to support concurrent distributed service composition with a type hierarchy and dynamically located services in spherical space.
