Description: Abstract
This paper talk about the communication protocol named LEACH. The protocol focuses on reducing the power consumption of wireless sensor networks, which can have significant impact on the overall energy dissipation of these networks. LEACH uses localized
coordination to enable scalability and obustness for dynamic networks, and incorporate data fusion into the routing protocol to reduce the amount of information that must be transmitted to the base station. Simulations show that LEACH can achieve as much as a factor of 8 reductions in energy dissipation compared with conventional routing protocols. In addition, LEACH is able to distribute energy dissipation evenly throughout
the sensors, doubling the useful system lifetime for the networks we simulated. Platform: |

Description: Estimating the positions of sensor nodes is a fundamental and
crucial problem in ad hoc wireless sensor networks (WSNs).
In this paper, an accurate node localization method for WSNs
is devised based on the weighted least squares technique with
the use of time-of-arrival measurements. Computer simulations
are included to evaluate the performance of the proposed
approach by comparing with the classical multidimensional
scaling method and Cram´ er-Rao lower bound. Platform: |

Description: 本文是一篇关于传感器网络安全的综述，详细地从各个层介绍了它的研究情况。-Wireless sensor networks(WSNs) use small nodes with constrained capabilities to sense,collect,and disseminate information in many types of applications.As sensor networks
become wide-spread,security issues become a central concern,
especially in mission-criticaltasks.In this paper,we identify
the
threats and vulnerabilities to WSNs and summarize the defense
methods based on the networking protocol layer analys is ?rst.Then we give a holistic overview of security issues.These issues are divided into seven categories:cryptography,keymanage-
ment,attack detections and preventions,securer outing,secure
location security,secure data fusion,and other security
issues.
Along the way we analyze thead vantages and disadvantages of
current secure schemes in each category.Inaddition,we also summarize the techniques and methods used in these categories,and point out the open research issues and directions in each
area. Platform: |

Description: Power consumption is an important design criterion in
the design of wireless sensor networks. Hybrid radio
frequency/free space optical wireless sensor networks (RF/FSO
WSN) have been proposed to reduce the energy consumption of
traditional RF-based sensor networks. This paper compares the
performance of such a hybrid sensor network against the wellknown
RF-based low energy adapting clustering hierarchy
(LEACH) WSN proposed in the literature. Network performance
is studied in terms of network lifetime and average network area
coverage. Simulations show that despite not employing data
aggregation, the RF/FSO WSN has a longer lifetime and larger
average network coverage when compared to the LEACH WSN Platform: |

Description: One of the most critical issues in the wireless sensor networks is the network s nodes limited availability of energy. The network lifetime strictly depends on its energy efficiency.
Clustering is a method to make the consumed energy efficient. LEACH is one of the fundamental clustering algorithms. In
this paper we have proposed an algorithm which extends LEACH by considering number of neighbors and remaining of the energy of each node to be a cluster head. We have also proposed to use gateway nodes in each cluster to enable the
cluster head to reduce its transmission radius within the cluster to achieve better power saving. We analyze and compared the proposed algorithm along with the LEACH, LEACH-c and MIMO the most recent extend over the LEACH and show that the proposed algorithm can prolong the lifetime of the network.
