Executive Summary

Wireless sensor networks are self-organizing systems with resource-constraints that are often deployed in inhospitable and inaccessible environments in order to gather data about some phenomenon in the outside world. For most sensor network applications, point-to-point reliability is not the main objective (Paradis & Qi, 2007); Instead, reliable delivery of the interesting event to the server has to be guaranteed (may be with a certain probability). The communication in such networks is unpredictable and failure-prone, even more so than in regular wireless ad hoc networks. Hence, it is vital to provide fault tolerant techniques for distributed applications in sensor network. Several approaches have been proposed in many recent studies to address the fault tolerance issue in application, transport and/or routing layers.
