A special issue of International Journal of Sensor Networks
Sensor networks are appealing to diverse services due to the distributed (redundant) nature of sensors. Redundancy has profound effects on the survivability of tasks at hand and is especially important to applications attempting to overcome the problem of single points of failure. Redundancy, however, increases the chance for component failure, increases the complexity of communication protocol, and renders system operation more complex in that the application program at hand must be perceived as it were running on a single system. With these in mind, the lack of embedded survivability requirements is a growing concern, as more critical services take advantage of advances in sensor technologies.
On the other hand, research studies in various fields of survivability, such as reliability, security, and fault tolerance, often develop different sets of terminologies and approaches with limited cross fertilisation among those properties, although the core problems across the fields are often similar. For instance, with respect to distributed agreement and data aggregation, the list of research articles in fault tolerance or security field is numerous, but there is very limited research in applying the results and maturity of one field to another. Additionally, many research studies apply inappropriate and/or complex cryptographic approaches, impose unrealistic assumptions, and tend to employ single or simplistic failure modes, rather than exploiting the benefits of hybrid fault models.
Accordingly, the main theme of this special issue on sensor networks is on cross-fertilisation of different survivability areas and pragmatic solutions. Of special interests are contributions that address: recovery, masking of fault and intrusion impacts, and co-existence of faults (hybrid fault models) with various severities for higher performance and survivability.
In the context of this theme, original unpublished manuscripts are solicited. General topics of interest include but are not limited to:
- Distributed algorithms for collaborative tasks
- Coordination and synchronisation
- Performance analysis of existing solutions
- Task allocation and scheduling
- Network intrusion tolerance
- Detection and self-organisation
- Routing algorithms
- Case studies of real world applications
- Hybrid fault modelling
- Unification of fault modeling of survivability properties
- Evaluation and validation of survivability
- Realisation and deployment of robust large-scale sensor networks
- Design for survivability
