Power consumption is one of the most critical challenges in wireless sensor networks, as sensor nodes are powered by batteries in most situations. Wireless communication is the main source of power consumption in a sensor node. Many energy aware protocols and algorithms have been proposed in the past few years. The basic idea of these methods is to reduce the data that nodes exchange and the time...
Wireless sensors networks is an active research topic. The sensor nodes (i.e. motes) are the main building blocks of these networks. There is a permanent concern for building more and more efficient motes in order to satisfy the demanding specifications of a sensor network. This paper introduces a new mote device: aceMOTE which is based on a 32 bit microcontroller. The hardware structure of the mote...
We present the RUNES architecture for reconfigurable embedded networked systems and wireless sensor networks. It is the first systems-level architecture for such networks to explicitly deal with heterogeneity in hardware platforms, link-layer technologies and networking protocols while offering a simple programming language independent set of APIs together with a component-oriented middleware for...
In this paper we investigate the benefits of power gating in wireless sensor nodes operating at a very low duty cycle. It is shown that the static power loss in such a node is significant portion of the total power consumption. Therefore, we have defined power-gated wireless sensor node architecture and developed a power gating mechanism to reduce the static power loss of its functional blocks. The...
