Description: Wireless sensor networks (WSN) consist of small
self-contained devices with computational, sensing and wireless
communication capabilities. They allow flexible, powerful, tetherless,
automated data collection and monitoring systems to be
created. Anticipated applications include environmental hazard
monitoring, forest fire detection, machine instrumentation, etc.
Many routing protocols have been proposed to facilitate data
transport from sensor nodes to a base station few of these protocols
have been formally verified or operationally deployed however.
The Minimum Cost Forwarding (MCF) routing protocol[1],
has been proposed. The application of MCF is restricted to
networks possessing a single sink node and multiple source
nodes.-Wireless sensor networks (WSN) consist of small

Description: 在很多无线传感器网络应用中，没有节点位置信息的监测信息往往毫无意义。当监测到事件发生时，关心的一个重要问题就是该事件发生的位置，如森林火灾监测，天然气管道泄漏监测等。这些事件的发生，首先需要知道的就是自身的地理位置信息。定位信息除了用来报告事件发生的地点外，还可用于目标跟踪、目标轨迹预测、协助路由以及网络拓扑管理等-In many wireless sensor network applications, there is no node location information of the monitoring information is often meaningless. When monitoring the event occurs, an important issue of concern is the location of the incident, such as forest fire monitoring, natural gas pipeline leak monitoring. These events, first of all need to know is their location information. Addition to its use location information of the sites based on the report of the incident, can be used for target tracking, target trajectory prediction, Xie Zhu routing and network topology management, etc.

Description: Wireless Sensor Networks (WSNs) have attracted much attention in recent years. The potential applications of WSNs
are immense. They are used for collecting, storing and sharing sensed data. WSNs have been used for various applica-
tions including habitat monitoring, agriculture, nuclear reactor control, security and tactical surveillance. The WSN
system developed in this paper is for use in precision agriculture applications, where real time data of climatologically
and other environmental properties are sensed and control decisions are taken based on it to modify them. The architec-
ture of a WSN system comprises of a set of sensor nodes and a base station that communicate with each other and
gather local information to make global decisions about the physical environment. The sensor network is based on the
IEEE 802.15.4 standard and two topologies for this application. -Wireless Sensor Networks (WSNs) have attracted much attention in recent years. The potential applications of WSNs

Description: A wireless sensor network (WSN) has important applications such as remote environmental
monitoring and target tracking. This has been enabled by the availability, particularly in
recent years, of sensors that are smaller, cheaper, and intelligent. These sensors are
equipped with wireless interfaces with which they can communicate with one another
to form a network. The design of a WSN depends significantly on the application, and it
must consider factors such as the environment, the application’s design objectives, cost,
hardware, and system constraints.

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.

Description: Sensor networks are emerging as a new tool for
habitat monitoring in nature preserves, monitoring and gathering events in hazardous environments, surveillance of buildings, and
surveillance of enemy activities in a battlefield environment. Nodes in a sensor network are severely constrained by energy, storage capacity and computing power. To prolong the lifetime of the sensor nodes, designing efficient routing protocols is critical.

Description: This paper is concerned with the application of
wireless sensor network (WSN) technology to long-duration
and large-scale environmental monitoring. The holy grail is a
system that can be deployed and operated by domain spe-
cialists not engineers, but this remains some distance into the
future. We present our views as to why this field has progressed
less quickly than many envisaged it would over a decade ago.
We use real examples taken from our own work in this field to
illustrate the technological difficulties and challenges that are
entailed in meeting end-user requirements for information
gathering systems. Reliability and productivity are key con-
cerns and influence the design choices for system hardware
and software. We conclude with a discussion of long-term
challenges for WSN technology in environmental monitoring
and outline our vision of the future
