The large-sized coal-fired power units characterizes as wide thermodynamic scale, huge equipment, large flow and mass, which results in distinct nonlinear feature in energy transmission, conversion and dissipation for specific equipment, system and process. There's highly coupling and nonlinear correlation between the energy consumption in power generation and the external environment, resources and...
This paper proposes a comprehensive routing protocol (CRP) based on the ant colony algorithm for the applications of Wireless Sensor Network (WSN). It is a protocol taking both the lifetime of network and the arrival rate of data packet into account. In CRP, multiple paths are found between source and destination, and sub-optimal paths are used occasionally referring to the probabilistic forwarding...
In Wireless Sensor Networks (WSN) the sensor nodes are usually battery-powered, for which the energy consumption must be minimized in order to extend their working time. The energy consumption of RF front-ends is dominant in the whole communication system, so we must consider how to minimize it in the design. In this paper, we describe four kinds of RF front-end architectures, energy model of each...
Routing is a key technique for wireless sensor networks (WSN). In order to improve the efficiency of routing in large-scale WSN, we propose Sink Routing Table (SRT) routing protocol, a routing protocol for WSN, in this paper. In SRT protocol, nodes aggregate data and use energy aware neighbor selection to route packets towards the target along an optimal path, each common node has no need to maintain...
This paper proposes a routing protocol for the applications of Wireless Sensor Network (WSN). It is a protocol based on the PEGASIS protocol but using an improved ant colony algorithm rather than the greedy algorithm to construct the chain. Compared with the original PEGASIS, this one, PEG-ant, can achieve a global optimization. It forms a chain that makes the path more even-distributed and the total...
Hardware co-processors are used for accelerating specific compute-intensive tasks dedicated to video/audio codec, encryption/decryption, etc. Since many of these data-processing tasks already have efficient software algorithms, one could reuse those to synthesize the co-processor IPs. However, such software algorithms are usually sequential and written in C/C++. High-level Synthesis (HLS) helps in...
With the advance of computer and communication technologies, wireless sensor networks (WSNs) are increasingly used in many aspects of our daily life. However, since the battery lifetime of WSN nodes is restricted, the WSN lifetime is also limited. Therefore, it is crucial to determine this limited lifetime in advance for preventing service interruptions in critical applications. This paper proposes...
Aiming at the shortage of LEACH protocol, a new routing protocol CDS-EBRP is proposed in this paper, CDS-EBRP fully takes account of the energy consumption of individual node and entire network, a rational transmission path from nodes of network to sink node is searched, Aiming at the network topology changes which are caused by the dead of cluster head nodes, the invalidation of cluster member nodes...
Aiming at the limited resources and data transmission redundancy of WSN, this paper proposes a novel data compression algorithm based on lifting wavelet transform, gives the rational design. The algorithm distributes the computing quantity which the lifting wavelet transform requires to all nodes, eliminates extra computing and data transmission, reduces the information redundancy of network, greatly...
This paper considers a circular high-density WSNs, which is divided into several homogeneous sectors. For a sector, the route nodes transmit data to base station (BS) along the sides of the sector and the radio of nodes can cover all areas of target area. The paper presents an energy-balance solution to balance the energy consumption, by adjusting transmission range with quality coverage under a FSCTA...
The number of functional units can have significant impact on both the performance and energy consumption of VLIW processors. This paper uses a design exploration approach to find optimal integer functional unit configurations for achieving the best EDP (energy delay product) results for different media applications. Our experimental results quantitatively indicate that the optimal number of integer...
