Journal of Network and Computer Applications, Elsevier, 2011, 34, pp.1380-1397. 10.1016/j.jnca.2011.03.022. hal-00593778 Y. Challal et al. / Journal of Network and Computer Applications 0 (2011  In wireless sensor networks, reliability is a design goal of a primary concern. To build a comprehensive reliable system, it is essential to consider node failures and intruder attacks as unavoidable phenomena. In this paper, we present a new intrusion-fault tolerant routing scheme offering a high level of reliability through a secure multi-path routing construction. Unlike existing intrusion-fault tolerant solutions, our protocol is based on a distributed and in-network verification scheme, which does not require any referring to the base station. Furthermore, it employs a new multi-path selection scheme seeking to enhance the tolerance of the network and conserve the energy of sensors. Extensive analysis and simulations using TinyOS showed that our approach improves many important performance metrics such as : the mean time to failure of the network, detection overhead of some security attacks, energy consumption, and resilience.
An intrusion-fault tolerant routing scheme proposed in REF offers a high level of reliability by a secure multipath routing construction topology and uses one-way hash chains to secure the construction of a multipath, many-to-one dissemination topology.
