A new wireless sensing network paradigm is presented for structural monitoring applications. In this approach, both power and data interrogation commands are conveyed via a mobile agent that is sent to sensor nodes to perform intended interrogations, which can alleviate several limitations of the traditional sensing networks. Furthermore, the mobile agent provides computational power to make ne...

In this position paper we argue that applications for the communication between vehicles do not require the functionality typically offered by mobile ad-hoc-networks or wireless sensor networks. Consequently the name Vehicular Ad-Hoc Network (VANET) is a misnomer leading practitioners and researchers astray. In order to make our point we briefly outline the characteristics of Mobile Ad-Hoc Netw...

Using mobile sensor networks has increased as well in recent years. It is because of the movement ability of sensor nodes which can be very useful in such networks. Having failure for network nodes occurs usually in wireless sensor networks which can be avoided by having the ability of movement in sensor nodes. It means that when a node fails consequently a hole appears in the coverage area of ...

Barrier coverage of a wireless sensor network is a critical issue in military and homeland security applications, aiming to detect intruders that attempt to cross the deployed region. While a range of problems related to barrier coverage have been investigated, little effort has been made to explore the effects of different sensor deployment strategies and mechanisms to improve barrier coverage...

The target tracking is one of the main issues in wireless sensor networks (WSNs). In the WSNs, the energy consumption is the most important factor for the network lifetime. In this paper, we utilize the advantage of the grid-based sensor networks to prolong the lifetime of the network. Therefore, we propose Grid-based Mobile Target Tracking Mechanism in Wireless Sensor Networks (GMTT). By the s...

Wireless Sensor Networks (WSNs) consist of spatially distributed wireless sensor nodes. Each sensor node cooperate with each other to monitor and collect data pertaining to physical or environmental conditions such as temperature, pressure, motion, sound, and other phenomena. Localization is an essential issue in wireless sensor networks because many applications require the sensor nodes to kno...

This document provides a preliminary analysis of the mechanisms for service and resource discovery in the Wireless Sensor Network (WSN) domain. These Service Discovery (SD) protocols form the cornerstone of the reconfiguration capability of the architecture and enable its effective management. We detail two proposals for incorporating this functionality in the Energy-efficient Sensor Network (E...

Wireless rechargeable sensor networks are becoming crucial and important in recent years for the advancement of wireless energy transmission technology. The previous research showed that not all of sensors can be recharged due to the limitation of energy capacity that mobile chargers can carry. If a sensor playing a critical role in a sensing task cannot function as usual due to exhausted energ...
