Energy Efficient and Fault Tolerant Multicore Wireless Sensor Network: E²MWSN

Wireless Sensor Network ´WSN´ is an active research field which explores many technological challenges, while the WSN node design is one of the most challenging areas. Nowadays, many wireless sensor nodes are implemented such as BTnodes, l´ESB/2 nodes, SmartTags, EYES node, TinyNode, Mote, Mica2, Tmote Sky, Atlas and Imote. Note that, all these wireless sensor nodes are quite similar in term of functionality. They are in general based on 8 or 16 bit RISC (Reduced Instruction-Set Computer) microcontroller (ATMEGA128 or MSP430) equipped with a unique Bluetooth or ZigBee wireless access medium having 200 meter LOS (Line Of Sight) range, and enable to implement a simple wireless sensor node. The robustness and the reliability of wireless sensor node are important for many applications such as smart care, smart home and outdoor applications. In this paper, we will present the first fault tolerant and configurable wireless sensor node based on multicore architecture with very low energy consumption comparing with the TelosB one. This new platform will drive new software approaches for the development of the rest of the upper layers, such as context-aware (resource-aware) which enables to minimize energy consumption and fault-tolerant WSN.
