Thesis Submitted

written by Mickey on 2006-09-19

Today I have submitted my Ph.D. thesis "Component-based adaptive Middleware for mobile distributed systems" to the examination office!

My thesis shows how the encapsulation of distributed systems middleware functionality into components can lead to an adaptive middleware system that -- by the means of a reflective architecture -- features dynamic adaptation to changing application requirements and to changing environmental conditions. Using the developed µMiddle architecture, you can add and modify

• application interfaces (e.g. RPC, Message Passing, Tuple Space),
• marshalling strategies (e.g. ASCII, Binary, XMLRPC, SOAP),
• stream operations (e.g. compression, encryption),
• transport protocols (e.g. TCP, UDP, ATP),
• service discovery modules (e.g. SDP),
• context awareness modules (battery, environmental lighting, CPUload),

and more directly within a running middleware system using a highly abstracted graph-based Meta-Object-Protocol that guarantees safe and consistent changes.
This kind of capability is of increasing importance for next generation mobile distributed systems and leads to more flexible middleware and application architectures.
Subject to the agreement of the board, I will get an appointment for the public defense of my thesis -- hopefully not later than December this year.
I want to acknowledge all of you who supported and believed in me in the past 5 years -- thanks!
