Abstract

In this paper we presented and classified various approaches for redundancy in the area of wireless sensor networks, related to sensing, communication and information processing. Sometimes an ally, sometimes a foe, redundancy is an inherent feature of sensor networks that has to be very carefully examined in order to improve important aspects of their functioning. Moreover, this paper presents two methodologies: one that implies both components of spatial redundancy and one that implies the use of temporal redundancy for achieving the objective of fault-tolerant and safe operation. In the end, the fields in which the redundancy could be applied with significant results are highlighted.
