Memory optimization, energy conservation, real-time scheduling and fault tolerance are the essential research topics in the wireless sensor network (WSN). In this paper, a memory-efficient, energy-efficient, real-time and fault-tolerant WSN system LiveOS is designed and implemented. Compared to the other systems, LiveOS has several typical features. Firstly, the optimized Rate-Monotonic Scheduling...
Memory optimization, energy conservation and fault tolerance are the essential research topics in the wireless sensor network (WSN). In this paper, a real-time, memory-efficient, energy-efficient and fault-tolerant WSN system LiveOS is designed and implemented. Compared to the other systems, LiveOS has several typical features. On the one hand, the optimized Rate-Monotonic Scheduling (RMS) mechanism...
An adaptive sliding mode backstepping fault-tolerant control is proposed for autonomous underwater vehicle(AUV) with thruster faults. Thruster faults are treated as uncertainties. Gaussian radial-basis-function networks are used to approximate these general uncertainties. In addtion, no Fault Detection and Diagnosis unit is needed in the proposed method.The controller can guarantee closed-stability...
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...
