In the wireless sensor network (WSN) literature, the use of a mobile sink is commonly viewed as one of the most successful means of load balancing and is often recommended as an effective defence against the so-called hot-spot phenomenon. In this paper, we investigate the real-world applicability of theoretical findings concerning sink mobility. The main(More)
Most of the existing works on the topic of sink mobility in wireless sensor networks (WSNs) are of purely theoretical nature. The aim of this paper is to discuss the challenges as well as potential benefits associated with the use of mobile sinks in WSNs that operate in space-constrained environments and employ real-world technology. Specifically, we(More)
● Security is built on top of three operational aspects of computer systems: confidentiality, integrity and availability ● (Distributed) Denial of Service (DoS) is an attack on the availability of data ● The denial-of-service effect is achieved by sending messages to the target that interfere with its operation, and make it crash, reboot, freeze or do(More)
Multipath routing is generally known for its highly effective performance in applications involving data streaming. However, to date, only a handful of research studies have looked at the performance of multipath routing in WSN systems. Moreover, according to our knowledge, there has been no earlier study on the use of multipath routing in ZigBee WSNs. In(More)
