Data muling using UAVs/drones is currently emerging as an alternative to the traditional traffic engineering techniques used in wireless sensor networks, when wireless communication is not an option or the least cost-efficient solution. This paper revisits the issue of traffic engineering in Internet-of-Things (IoT) settings, to assess the relevance of using UAVs for the persistent collection of sensor...
A major issue in many applications of Wireless Sensor Networks (WSNs) is ensuring security. Particularly, in military applications, sensors are usually deployed in hostile areas where they can be easily captured and operated by an adversary. Most of security attacks in WSNs are due to the lack of security guaranties in terms of authentication, integrity, and confidentiality. These services are often...
The obstacles in the transmission path, the non-isotropic antennas and the impact of environmental phenomena in WSNs may result to unreliable and unpredicted radio transmission, and therefore affect the evaluation of applications which specifically require high coverage and connectivity. Such an issue is known by radio irregularity which greatly impacts algorithms performing under simplistic radio...
Wireless Sensor Networks (WSNs) have witnessed a dramatic increase of the interest of the research community in the last couple of decades. Many applications are being deployed on the base of distributed tiny sensors ranging from mobile target surveillance to intelligent home networking. Research in the WSNs field has always an important goal which is increasing the lifetime of the network. This is...
