Description: The sensor nodes of a wireless grain depot
surveillance system are deployed in crystal grids, which provide
lot of valid position information. To avoid the energy
consumption unbalance of the single hop routing model adopted
by LEACH protocol, a novel hybrid routing model is proposed
in this paper. Multi-hop routing is introduced into the distant
field nodes through right angle transferring of approximate
equivalence consumption path. And the average energy
consumption is used as a threshold of selecting intermediate
transferring nodes to minimize total variance of node s energy
consumption, so that balance the whole network. Simulations
show that the hybrid model eliminates hot spots within cluster
and prolong the lifetime ofWSN. -The sensor nodes of a wireless grain depot

Description: 提出了基于无线传感器网络的浮标网络水下GPS定位系统模型，分析了
该模型的结构、功能以及工作过程，并从几何角度探讨了水下目标的声学定位算
法。结合Range-Free算法与分布式算法的思想，设计了一种传感器节点自定位算
法，称为BSR（Beacons Signal Ring）定位算法，并对该算法的性能进行了评估与
比较。该算法在锚节点处的信标信号中引入能量等级的机制，无需相邻传感器节
点间信息交换，有效降低了算法复杂度与通信开销。性能分析结果显示，该算法
性能良好，在应用环境下相比于APIT算法与质心算法具有更低的位置估计误差。
论文还研究了基于双元检测传感器的协作式的目标跟踪策略，对相应的跟踪过程
进行了描述。提出了使用加权质心算法的目标位置估计模型，以及线性预测机制，
使跟踪过程具有较小的计算和通信代价。-In this thesis,we presents a buoy network of underwater GPS positioning system
model based on the wireless sensor network.The structure,function and process in the
model were analyzed.Underwater target acoustic localization algorithm were explored
through geometry way.Combined with the idea of Range-Free algorithm and distributed
algorithm,a sensor nodes self-localization algorithm were designed,which called BSR
(Beacons Signal Ring)localization algorithm,the algorithm performance evaluation and
comparison has also been presented.The algorithm use a small number of anchor nodes.
Each anchor emits beacons at different power levels.This mechanism does not required
information exchange between neighboring sensors,and reduced the complexity of the
algorithm and communication overhead effectively.The results of performance analysis
showed that BSR provides a lower position estimation error than APIT and Centroid
under a wide range of conditions.The thesis introduced process of ta Platform: |

Description: Monitoring applications define an important
class of applications used in wireless sensor networks.
In these applications the network perceives
the environment and searches for event
occurrences (phenomena) by sensing different
physical properties, such as temperature, humidity,
pressure, ambient light, movement, and presence
(for target tracking). In such cases the
location information of both phenomena and
nodes is usually required for tracking and correlation
purposes. In this work we summarize most
of the concepts related to localization systems for
WSNs as well as how to localize the nodes in
these networks (which allows the localization of
phenomena). By dividing the localization systems
into three distinct components — distance/angle
estimation, position computation, and localization
algorithm — besides providing a didactic
viewpoint, we show that these components can
be seen as subareas of the localization problem
that need to be analyzed and studied separately. Platform: |

Description: LEACH [1] is an autonomous adaptive clustering protocol that distributes the
energy load evenly among the sensors in the network using randomization. The
nodes organize themselves into local clusters, with one node acting as the local
base station or cluster head. In order to not drain the battery of a single sensor
randomized rotation of the high-energy cluster head position such that it rotates
among the various sensors. Once the cluster head has all the data from the nodes in
its cluster, the cluster head node aggregates the data and then transmits the
compressed data to the base station. Since it compress the amount of data being
sent from the clusters to the base station, energy dissipation is reduced and system
lifetime is thus enhanced.
