Description: WSNs being energy constrained systems, one major problem is to employ the sensor nodes in such a manner so as to ensure maximum coverage and connectivity with minimal or optimal number of nodes and furthermore elongate network lifetime with maximum energy utilization.
The problem addressed has been tackled for 1-D linear array and further extended to 2-Dimensions as stated in the next slides.

Description: 这篇论文介绍了一种有效的3D笔刷模型，模仿中国毛笔的写字方式，能够运用于各种程序。-This paper presents a novel 3D brush model consisting of a skeleton and a surface, which is deformed through constrained energy minimization. The main advantage of our model over existing ones is in its ability to mimic brush flattening and bristle spreading due to brush bending and lateral friction exerted by the paper surface during the painting process. The ability to recreate such deformations is essential to realistic 3D digital painting simulations, especially in the case of Chinese brush painting and calligraphy. To further increase realism, we also model the plasticity of wetted brushes and the resistance exerted by pores on the paper surface onto the brush tip. Our implementation runs on a consumer-level PC in real-time and produces very realistic results. Platform: |

Description: Abstract—In this paper, we consider distributed estimation of
a noise-corrupted deterministic parameter in energy-constrained
wireless sensor networks from energy-distortion perspective.
Given a total energy budget allowable to be used by all sensors,
there exists a tradeoff between the subset of active sensors and
the energy used by each active sensor in order to minimize the
estimation MSE. To determine the optimal quantization bit rate
and transmission energy of each sensor, a concept of equivalent
unit-energy MSE function is introduced. Based on this
concept, an optimal energy-constrained distributed estimation
algorithm for homogeneous sensor networks and a quasi-optimal
energy-constrained distributed estimation algorithm for heterogeneous
sensor networks are proposed. Moreover, the theoretical
energy-distortion performance bound for distributed estimation
is addressed and it is shown that the proposed algorithm is
quasi-optimal within a factor 2 of the theoretical lower bound.

Description: —As WSN is a resource-constrained network,
especially the limited energy, so it must maintain smaller
router information and reduce the energy consumption as
much as possible. This paper briefly introduces the wireless

selecting cluster node ,and through the use of limiter the
number of nodes in each cluster to balance the energy
depletion of each node. It could balance energy
consumption and prolong the lifetime of sensor network
through the use of algorithm. Emulation result indicates it
is effective.-—As WSN is a resource-constrained network,

Description: Turbo codes have recently been considered for
energy-constrained wireless communication applications, since they facilitate a low transmission energy consumption. How-
ever, in order to reduce the overall energy consumption, lookup table-log-BCJR (LUT-Log-BCJR) architectures having a low
processing energy consumption are required. In this paper, Authors decompose the LUT-Log-BCJR architecture into its most funda-
mental add compare (ACS) operations and perform them using a novel low-complexity ACS unit. We demonstrate that the proposed
architecture employs an order of magnitude fewer gates than the most recent LUT-Log-BCJR architectures, facilitating a 71 energy consumption reduction. Compared to state-of-the-art maximum logarithmic Bahl-Cocke-Jelinek-Raviv implementations, proposed approach facilitates a 10 reduction in the overall energy consumption at ranges above 58 m.-Turbo codes have recently been considered for

Description: Localization is one of the key techniques in wireless sensor network. The location estimation methods can be classified into target/source localization and node self-localization. In target localization, we mainly introduce the energy-based method. Then we investigate the node self-localization methods. Since the widespread adoption of the wireless sensor network, the localization methods are different in various applications. And there are several challenges in some special scenarios. In this paper, we present a comprehensive survey of these challenges: localization in non-line-of-sight, node selection criteria for localization in energy-constrained network, scheduling the sensor node to optimize the tradeoff between localization performance and energy consumption, cooperative node localization, and localization algorithm in heterogeneous network. Finally, we introduce the evaluation criteria for localization in wireless sensor network. Platform: |

Description: In mathematical optimization, constrained optimization (in some contexts called constraint optimization) is the process of optimizing an objective function with respect to some variables in the presence of constraints on those variables. The objective function is either a cost function or energy function which is to be minimized, or a reward function or utility function, which is to be maximized. Constraints can be either hard constraints which set conditions for the variables that are required to be satisfied, or soft constraints which have some variable values that are penalized in the objective function if, and based on the extent that, the conditions on the variables are not satisfied.
