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...
Multithreaded operating system (OS) is essential to be used for many wireless sensor network (WSN) applications. However, the RAM consumption of the multithreaded OS is high. Thus, it is infeasible to apply the multithreaded OS on many high RAM constrained wireless sensor nodes (WNs). To address this challenge, several memory optimization strategies are investigated in this paper. On one hand, the...
Wireless Sensor Networks (WSNs) have played an important role in diverse domains. However, programming on WSN nodes are quite hard because currently there exist no standard software and hardware platforms in WSN. Thus it's essential to build a software infrastructure that can provide a decent development environment to the users. One sound choice to achieve this objective is to deploy embedded Java...
Wireless sensor networks (WSNs) have played an important role in widespread applicable domains. However, the programming and reprogramming processes in WSNs are complicate, this results from the diverse software and hardware platforms in WSNs, the constraint memory and energy resources on sensor nodes as well as the unstable wireless transmission process, etc. Thus, it's significant to design and...
