On the other hand, nQ WF-MAC's groomed resource usage mechanism insulates it from higher increasing rate of medium access delay.
Transmission capacity was defined as the maximum density of the transmitting node to satisfy outage probability and data rate on medium access control (MAC) layer performance.
The purpose of a transmission schedule is to control link transmission powers and rates, regulate medium access and provide adequate capacity for all network traffic.
The basic techniques applied for energy efficient networks are: (a) energy efficient protocols for routing, medium access, hand-off and (b) Adaptive Link Rate (ALR) techniques that scale link rate and utilize sleep states for energy-proportional computing [55].
Presti et al. [17] consider cross-layer flow rate, routing, and medium access control in a cognitive radio network context and, for the first time, derived a fully distributed solution.
Theoretical analysis and simulation results show that our proposed MAC protocol realizes the function of medium access control and attains a maximum data rate of 18.3 Gbit/s, which is 2 times higher than 5.78 Gbit/s, the theoretical maximum data rate of IEEE 802.15.3c standard.
We demonstrate using simulations that AdAMAC outperforms the best medium access control algorithms designed for higher traffic rates in terms of packet delivery ratio and latency and has a similar energy cost to them.
Optimal channel assignment would simultaneously involve the choices of routing metric, rate control, power control, and medium access control (MAC).
The unique characteristics of the underwater acoustic channel, such as long propagation delay, delay variance, and high bit error rate, present challenges for the medium access control (MAC) protocol design in UANs.
The IEEE 802.15.4 specifies10] specifies the sub-layer medium access (MAC) and the physical layer for low-rate wireless personal area networks.
