With the emergence of smart, sensor-equipped mobile devices, the gathering and processing of data concerning the everyday lifestyles of the people using these devices has become a matter of course within the field of HCI. New standards in mobile technologies provide new opportunities for empirical studies, which allow researchers to explore people’s everyday lives unobtrusively. Furthermore, mo...

Using a mobile sink is a type of promising application in wireless sensor networks (WSNs). To minimize the number of static nodes that are awake while the mobile sink is gathering data, it is beneficial to use cluster heads (CHs) for network management and operation, thereby saving energy in communication. During the network design, deciding an appropriate number of CHs is an important thing to...

In Wireless sensor networks data aggregation with hundreds and thousands of sensor nodes is very complex task. Recently, mobile agents have been proposed for efficient data dissemination in sensor networks. In the traditional client/server based computing architecture, data is collected from multiple sources and forwarded to destination for further processing. It requires high bandwidth, wherea...

Sensor nodes located in the vicinity of a static sink drain rapidly their batteries since they have to carry more traffic burden. This situation results in network partition, holes as well as data losses. To mitigate this issue, many research proposed the use of mobile sink in data collection as a potential solution. However, due to its speed, the mobile sink has very short communication time t...

This chapter reviews a number of emerging topics pertaining to a data-centric view of wireless sensor networks. These topics include data-driven routing, tracking mobile objects, constructing and maintaining reporting trees, dynamic evolution of a monitoring region for moving targets (mobicast), disseminating monitoring tasks, data gathering, receiving reports from a particular area of interest...

We are working to develop an information gathering system comprising a mobile robot and a wireless sensor network (WSN) for use in post-disaster underground environments. In the proposed system, a mobile robot carries wireless sensor nodes and deploys them to construct a WSN in the environment, thus providing a wireless communication infrastructure for mobile robot teleoperation. An operator th...

Wireless Sensor Networks are highly definite in nature when it comes to their different applications and their pattern of energy consumption is highly discussed research issue. In order to deal with above issues, mobile agents are introduced to the network. These agents are movable codes that roam around the network for data gathering related tasks. The route followed by these agents is called ...

Wireless Sensor Networks is a fast leading technology which has showed up many opportunities in the field of data reporting and monitoring. It has a collection of sensor nodes which can report data to the base station. It increases energy consumption and traffic. So to avoid network traffic and to prolong network lifetime clustering scheme is used. Mobile sinks can easily move to the deployed a...

We propose an opportunistic routing scheme for wireless sensor networks operating in volatile environments. In particular, we consider a sensor field for sensing and reporting on buildings during fires, where sensors are progressively being destroyed by the fire. We envisage firefighters equipped with small computers which can act as mobile sink nodes, offering transient shorter routes for rela...

Mobile enable Wireless Sensor Network (mWSN) has been proposed to realize large-scale information gathering via networking wireless sensors and mobile sinks. Some fundamental design parameters in mWSN have been investigated in this article, such as cluster size, sink velocity, transmission range, and packet length. Our contributions include: 1) We propose to use multihop forwarding to form a cl...
