Abstract
In wireless sensor networks, fault tolerance represents a key issue and a design goal of primary concern. Indeed, nodes in wireless sensor networks are prone to failures due to energy depletion or hostile environments. Multipath routing protocols are a category of solutions which enables the network to operate properly despite of faults. In this paper, we present a new multipath routing protocol which provides strong fault tolerance by increasing the number of constructed paths up to three times in some scenarios. Our protocol relies on a new multipath construction paradigm that we have defined specifically for heterogeneous WSN. We call this paradigm: energy-node-disjointness. Our approach leverages a reasonable increase in the cost of the network to a longer network lifetime and a higher resilience and fault tolerance.
