It has been well recognized that network transmission constitutes a large portion of smartphone energy consumption, mainly because of the tail energy caused by cellular network interface. Traffic offloading has been proposed to reduce energy by letting a smartphone offload network traffic to its neighbors in vicinity via low-power direct connections (e.g., WiFi Direct or Bluetooth). Our experiments...
Although wireless sensor networks are widely used in recent years, it remains a big security risk in the transmission of information and energy consumption of the nodes. By summarizing the existing wireless sensor networks attack measures, this paper proposes a way to attack wireless sensor networks by wireless injection, at different times fake nodes is disguised as acquisition nodes and transmission...
Code offloading has been proposed to improve the performance and energy-efficiency of mobile devices by sending heavy computation tasks to resourceful cloud, instead of executing all tasks on local mobile devices. Unfortunately, current code offloading techniques are not efficient enough because of high communication cost. In this paper, we propose a novel code offloading strategy with cellular traffic...
After a decade of extensive research on application-specific wireless sensor networks (WSNs), the recent development of information and communication technologies make it practical to realize software-defined sensor networks (SDSNs), which are able to adapt to various application requirements and to fully explore the resources of WSNs. In SDSNs, wireless sensor nodes can be dynamically reprogrammed...
Energy consumption is a fundamental issue in today's data centers as data continue growing dramatically. How to process these data in an energy-efficient way becomes more and more important. Prior work had proposed several methods to build an energy-efficient system. The basic idea is to attack the memory wall issue (i.e., the performance gap between CPUs and main memory) by moving computing closer...
Stochastic encoding represents a value using the probability of ones in a random bit stream. Computation based on this encoding has good fault-tolerance and low hardware cost. However, one of its major issues is long processing time. We have to use a long enough bit stream to represent a value to guarantee that random fluctuations introduce only small errors to final computation results. For example,...
Cooperative communication (CC) has been proposed to achieve spatial diversity without requiring multiple antennas on a single device. Many efforts in exploiting the benefits of CC focus on improving the performance in terms of outage probability and channel capacity. However, the energy efficiency of CC, which is critical for the applications with energy constraints, has been little studied. In this...
In this paper, The Monte Carlo localization algorithm based on RSS is proposed, which calibrate the weights between mobile node and each anchor nodes by using the distance between anchor nodes and mobile nodes measured RSS values. This method avoids the filter conditions of MCL method which makes it impossible to get enough valid samples and resample to bring a large number of calculations. Simulation...
Soil erosion on slope was one of the key points in soil erosion research. Soil texture was one important factors influencing soil erosion. By indoor runoff scouring experiments, runoff erosion characteristics on the slopes with two different soils were studied systematically to reveal the influence of soil texture on soil erosion on the slope. Results indicated that the sediment yield increased fluctuate...
Thread-Level Speculation (TLS) has shown great promise as an automatic parallelization technique to achieve high level performance by partitioning a sequential program into threads, which are expected to be optimistically executed in parallel. In this paper, we propose a load-balancing approach to save energy using dynamic voltage scaling. By scaling the voltage of processors running short threads,...
In this paper, a mobile mechanism with driving capability and detecting function is proposed for in-pipe inspection task. Based on this mechanism, a robot is designed and fabricated. The advantage of this robot is that it has mobile ability in the pipe and detecting function for inspection, while only one DC motor is installed. This results in low energy consumption and low cost to make. The robot...
