+ | My PhD research focused on investigating programming language support to deal with the effects engendered by partial failures in mobile ad hoc networks (MANETs). In MANETs many partial failures are the result of temporary network partitions due to the intermittent connectivity of mobile devices. Some of these failures will be permanent and require application-level failure handling. However, it is impossible to distinguish a permanent from a transient failure. Leasing provides a solution to this problem based on the temporal restriction of resources. | ||

- | I am interested | + | The dynamic nature of ambient oriented applications makes it impossible to structure them as monolithic programs with a fixed input and output. Instead, a distributed event-driven architecture is required. Current event-driven architectures require distributed application components to react to events via a carefully crafted network of observers, event handlers or callback mechanisms which are scattered throughout the application code and can be triggered at any point in time. Such architectures are hard to develop, understand |

+ | Our everyday environment will soon be pervaded with RFID tags, tiny chips that can be integrated into any physical object. The tags can store and distribute information about the object or its environment. RFID technology is a key technology in developing pervasive context-aware applications. | ||
+ | |||
+ | I am investigating new programming abstractions to develop | ||
- | The goal of my research | + | Currently programming such applications is problematic. Communicating with RFID tags is prone to many failures as the connections with tags are extremely volatile and RFID tags have a small range of operation. State-of-the-art RFID applications heavily rely on infrastructure and merely employ RFID tags as digital barcodes, not exploiting the writable memory on the tags. As a consequence mobile RFID-enabled applications have to be developed in an ad hoc way, building upon low-level hardware abstractions leaving the developer to deal with RFID hardware characteristics manually. |

+ | Nomadic networks fill the gap between fixed networks and mobile ad hoc networks (MANETs) as they consist of a group of mobile devices that can move around dynamically while trying to maintain a connection with a fixed infrastructure. My research focusses on the coordination of nomadic services by making use of workflows as they provide an additional layer of abstraction such that interactions among application components can be specified on a higher level and be reused because of their loose coupling with the fine-grained application logic. Unfortunately, | ||

+ | |||
+ | AmbientTalk is a programming language which treats disconnections at the very heart of its computational model. Moreover, the language supports dynamic service discovery which is opportune for nomadic networks. Although this language is suited for writing applications for MANETs, the orchestration of these applications is still programmed in an ad hoc manner. Complex nomadic applications that consist of asynchronously executing distributed services become hard to develop, understand and reuse. I am currently working on the addition of an abstraction layer on top of AmbientTalk which implements | ||

- | In an Ambient Intelligent setting, various kinds of hardware are involved, each with its own characteristics. To allow abstraction over the different devices, a standard virtual machine approach is not feasible because it is not possible to abstract over all the devices at the same time. Instead, each device will require an individually adapted virtual machine. | ||
- | |||
- | This reseach proposes a new way to develop virtual machines for Ambient Intelligence. Instead of manually modifying the virtual machine for of a particular device, the virtual machine can be generated by composing reusable modules. The first step is to determine the set of modules that can be used to build a virtual machine. The next step is to find implementation and composition techniques that guarantee the correctness and efficiency of the generated virtual machine. | ||
