Machine-to-Machine (M2M) communication relies on the physical objects (e.g., satellites, sensors, and so forth) interconnected with each other, creating mesh of machines producing massive volume of data about large geographical area (e.g., living and non-living environment). Thus, the M2M is an ideal example of Big Data. On the contrary, the M2M platforms(More)
Multi-hop communication in Underwater Acoustic Sensor Network (UASN) brings new challenges in reliable data transmission. Recent work shows that data collection from underwater sensor nodes using Autonomous Underwater Vehicle (AUV) minimizes multi-hop data transmission, improving energy efficiency in UASN. However, due to continuous movements, AUV has(More)
A fundamental challenge in Device-to-Device Communication (D2D) is that the quality of radio links is subject to high transmission power with high channel impairments. This channel impairment leads to higher error rates and temporary path losses that result in the retransmission of data frames and ultimately limits the efficiency of wireless networks. With(More)
