Abstract: As dense Wireless Sensor Networks (WSNs) are increasingly vulnerable to fault, network must continue processing data without affecting the faulty node. Fault aware routing is an effective way to mitigate such a scenario. To this end, we present a de-Bruijn graph based Multipurpose Architecture and Routing Protocol (MARP) which has all the properties of an efficient WSN. The MARP supports multicast routing, broadcasting, fault detection and efficient fault-tolerance. Its unique architecture makes it easily scalable and provides easy three-dimensional to two-dimensional mapping. Furthermore, we show that, depending on the fault-tolerance capability one wants, design requires higher redundancy. A small experiment of de-Bruijn graph based routing protocol is also presented with mica2 motes to check its feasibility in a real-life scenario.
