Abstract:
Next-generation wireless sensor networks (xWSN) have applications in many emerging wireless technologies,
such as fifth-generation, internet-of-things, device-to-device communications, e-health, e-agriculture, etc. For
most of these xWSN applications, network reliability and robustness against failures are crucial considerations.
In this paper, an appropriate network restoration model is developed to help achieve network protection and/or
restoration for xWSN in the event of link failures. In the model, effective network restoration is achieved by
investigating efficient pre-configured-cycle (p-cycle)-based restoration solutions for the xWSN. Furthermore, to
achieve significant improvement in the capacity efficiency of the p-cycle solutions realised, the concepts of pcycle
selectivity, load redistribution and the use of single p-cycles for double failure restoration are investigated
and incorporated in the network restoration design. The restoration model developed, alongside the various
improvement concepts incorporated, is shown to achieve better performance in terms of average path length
and total capacity cost when compared with similar restoration models for modern wireless communication
applications.
