TL;DR: Simulations show that this discipline presents the best results in terms of sensor-to-sink slot distance, even if they require a few more slots than breadth-first in multi-frame scenarios.
Abstract: Energy-efficiency and latency requirements in alarm-driven Wireless Sensor Networks often demand the use of TDMA protocols with special features such as cascading of timeslots, in a way that the sensor-to-sink delay bound can stay below the duration of a single frame. However, this single TDMA frame should be as small as possible. The results presented in this paper, point to the conclusion that a largest-distances-first strategy can achieve the smallest single frame sizes, and also the lowest frame size variations. A quite simple distributed version of this algorithm is presented, which obtains the same results of its centralized version. Simulations also show that this discipline presents the best results in terms of sensor-to-sink slot distance, even if they require a few more slots than breadth-first in multi-frame scenarios.

03 Oct 2011TL;DR: This chapter addresses the problem of minimizing the number of addition and subtraction operations in a CMVM operation and introduces a hybrid algorithm that incorporates efficient techniques and describes how the hybrid algorithm can be modified to handle a delay constraint.
Abstract: The last two decades have seen tremendous effort on the development of high-level algorithms for the multiplierless design of constant multiplications, i.e., using only addition, subtraction, and shift operations. Among the different types of constant multiplications, the multiplication of a constant matrix by an input vector, i.e., the constant matrix-vector multiplication (CMVM) operation, is the most general case and occurs in many digital signal processing (DSP) systems. This chapter addresses the problem of minimizing the number of addition and subtraction operations in a CMVM operation and introduces a hybrid algorithm that incorporates efficient techniques. This chapter also describes how the hybrid algorithm can be modified to handle a delay constraint. The experimental results on a comprehensive set of instances show the efficiency of the hybrid algorithms at both high-level and gate-level, in comparison to previously proposed methods.

17 Sep 2017TL;DR: Information Governance as defined by Gartner is the “specification of decision rights and an accountability framework to encourage desirable behavior in the valuation, creation, storage, use, archival and deletion of information.
Abstract: Information Governance (IG) as defined by Gartner is the “specification of decision rights and an accountability framework to encourage desirable behavior in the valuation, creation, storage, use, archival and deletion of information. Includes the processes, roles, standards and metrics that ensure the effective and efficient use of information in enabling an organization to achieve its goals”.

18 May 2008TL;DR: This paper investigates the performance of the multi-band low noise amplifier (LNA) based on the concept of using multiple cascode transistors for band selection; thus, avoiding switches in the signal path.
Abstract: In this paper we investigate the performance of the multi-band low noise amplifier (LNA) based on the concept of using multiple cascode transistors for band selection; thus, avoiding switches in the signal path. We also show that this circuit can perform mixing of two signal bands with two different local oscillator frequencies, which provides great flexibility in the design of dual-band RF front-ends. The operation of both as LNA and as combined LNA/mixer is demonstrated by simulation.
