On Sensor Network Reconfiguration for Downtime-Free System Migration

On Sensor Network Reconfiguration for Downtime-Free System Migration

Many state-of-the-art wireless sensor networks have been equipped with reprogramming modules, e.g., those for software/firmware updates. System migration tasks such as software reprogramming, however, will interrupt normal sensing and data processing operations of a sensor node. Although such tasks are occasionally invoked, the long time of such tasks may disable the network from detecting crit...

Simple Deadlock-Free Dynamic Network Reconfiguration

Dynamic reconfiguration of interconnection networks is defined as the process of changing from one routing function to another while the network remains up and running. The main challenge is in avoiding deadlock anomalies while keeping restrictions on packet injection and forwarding minimal. Current approaches fall in one of two categories. Either they require the existence of extra network res...

Methods and techniques for disruption-free network reconfiguration

Part I: A Theory for Deadlock-Free Dynamic Network Reconfiguration

This paper develops theoretical support useful for determining deadlock properties of dynamic network reconfiguration techniques and also serves as a basis for the development of design methodologies useful for deriving deadlock-free reconfiguration techniques. It is applicable to interconnection networks typically used in multiprocessor servers, network-based computing clusters and distributed...
