Nowadays most of the wireless sensor network management modes have a shorter lifetime because adopting the way of transferring management information to each other, which thus consuming energy too fast. This paper is aimed at making use of mobile and computerized characteristics of the mobile agent and considering the capacity factors to establish wireless sensor network management model with low...
Wireless sensor network (WSN) is the network which is composed of a large number of intelligent sensor nodes, it has the ability of self-organizing network routing, therefore, it has been widely used. Building wireless sensor networks is the key to WSN nodes.

Detecting and reacting to faults is an indispensable capability for many wireless sensor network applications. Unfortunately, implementing fault detection and error correction algorithms is challenging. Programming languages and fault tolerance mechanisms for sensor networks have historically been designed in isolation. This is the first work to combine them. Our goal is to simplify the design of...
The performance evaluation of wireless sensor network based on passive monitoring restricted by two respects: first, passive monitoring trace is incomplete, because monitors can not capture every transmission in the network. Second, the information directly extracted from trace is insufficient. Performance evaluation always needs some implicit information, e.g., packet reception. To solving the problems...
Recently, wireless sensor network is widely used. The deployment of WSN in the field, however, is still restricted due to limited energy supply, limited computing power, limited buffer size, and packet delay. In this paper we present a new cluster model and polling protocol integrating the schedule polling and low power listening scheme. The new clustering approach allows short routing between the...
In wireless sensor networks, sensor nodes are capable of not only measuring real world phenomena, but also storing, processing, and transferring these measurements. Many techniques have been proposed for storing and retrieving data in these networks. These methods are classified into three main categories. Data-centric storage is the most important one. The name comes from the fact that data's storage...
Wireless Sensor Network has limited battery power and computational power, leads to increased complexity. A better data aggregation framework on wireless sensor networks gives an efficient battery power and improved lifetime. This can be achieved by making the framework as middleware for aggregating data, measured by a number of nodes within a network. In this paper the performance of TAG in terms...
Designing a QoS-aware, yet energy-saving routing protocol for WSNs is a notoriously hard problem. However, the outstanding interest for this technology, and the growing number of envisioned applications, motivate the need to introduce the notion of Quality of Service (QoS) in these networks. This paper introduces EDEAR (Energy and Delay Efficient Adaptive Routing), an adaptive routing algorithm based...
In some applications of WSN, each node can communicate with the base station, if each node communicates with base station directly, there are will a lot of duplication of information and cause waste of nodes' energy. For this reason, we put forward Data Query Protocol Based on Minimum Spanning Tree (QPMST) , QPMST protocol can create a minimum spanning tree with sink as root and other nodes as descendants,...
Wireless sensor and actor networks are becoming a basis for a rapidly increasing range of applications in industrial measurement-control (M&C) systems. Each application has different requirements in terms of M&C task, node functionalities, network size, complexity and cost; therefore, it is worthwhile time investment to design and implement a middleware for wireless sensor and actor networks...
During a crisis situation, the incident commanders have to tackle several problems simultaneously, e.g., (1) the monitoring of a crisis evolution, (2) guiding and tracking of rescue persons and intervention robots, (3) monitoring rescue persons' health, etc. Thus, several solutions based on wireless sensor networks (WSNs) and cellular networks have been proposed. However, the real life experience...
Wireless Sensor Network (WSN) is an emerging technology that shows great promise for various futuristic applications both for mass public and military.

Service gateways (SGs) are a promising approach to integrate wireless sensor and actuator networks (SANETs) with pervasive infrastructure over Internet by encapsulating distributed physical sensor and actuators into regular objects. Typically, SGs for SANETs are assumed to know operational environment in advance at design time with limited awareness of operational SANET conditions and, in the meanwhile,...
Many recent applications deal with continues flows of data (data streams). One important area of applications that is based on data streams is the area of Wireless Sensor Networks (WSNs) applications.
