To ensure long network life-time, the duty-cycle of wireless sensor networks is often set to be low. This brings with itself the risk of either missing a sent packet or delaying the message delivery and dissemination depending on the duration of the duty-cycle and number of hops. This risk is increased in wireless sensor applications with hybrid architecture, in which a static ground wireless sensor...
Although in recent years many research activities have been carried out on underwater communication, still many challenges need to be tackled to make the underwater communication suitable for real applications. To this end, availability of an open and well-designed platform and performing real-world experiments are crucial. In reality, the real-world experiments have proved to be much more difficult...
In most application scenarios of wireless sensor networks (WSN), sensor nodes are usually deployed randomly and do not have any knowledge about the network environment or even their ID's at the initial stage of their operations. In this paper, we address the clustering problems with a newly deployed multi-hop WSN where most existing clustering algorithms can hardly be used due to the absence of MAC...
