Resilience and Post‐Deployment Maintenance
Sharief Oteafy, Hossam S. Hassanein · 2014
This chapter overviews the recent work on wireless sensor network (WSN) operational changes post-deployment. It addresses the multiplicity of factors that pose potential hindrances to WSN performance, and presents a classification on the basis of their impact in different design phases of the network. Failures in sensing systems, and wireless networks in general, have been tackled in the literature extensively. When merged together, a new class of (inherently complex) problems has been aggregated to form the field of resilience in WSNs. Traditionally, limited deployments in terms of size and scale, allowed practitioners to re-visit the field of deployment to perform maintenance. Moreover, most initial deployments were deterministic in their region of operation, and witnessed limited/no mobility. Recent improvements in nodal (operational) capacity, toward improving performance, have facilitated new dimensions for mobility as an aid for network design in addition to connectivity and coverage.
