“…Another neighborhood maintenance protocol, proposed in [34], has the mobility awareness feature; however, it is inefficient for the intended MANETs due to the additional acknowledgement message overheads. Furthermore, there are several recent studies offering interference solutions via directional or smart antennas as in [35][36][37][38], but implementation of directional antennas for crowded MANETs require more complex and costly hardware. Hence, these protocols are also not applicable to the intended MANET scenarios.…”

Mobile ad-hoc networks (MANETs) have been widely employed in many fields including critical information delivery in open terrains as in tactical area, vehicular or disaster area network scenarios. To provide effective network maintenance for those MANETs, it is essential to adopt proper control communication methods, which provide reliable delivery of network information. However, it is difficult to provide control communication that meets the quality of service requirements due to the broadcasting of control messages and dynamic nature of MANETs. Interference is one of the major problems that degrades this service quality, especially for the networks deployed in open terrain environments. Moreover, large and dense MANET scenarios further complicate this problem. Even though many communication methods have been proposed in the literature, a satisfactory one for periodic and broadcast delivery of control packets considering the interference awareness and at the same time yielding high reliability, goodput, energy efficiency still does not exist for MANETs. To that end, we present a new control communication protocol, which is referred to as the Interference-Aware Periodic Broadcast Messaging (IPBM) protocol, for those MANETs deployed in interference-rich open terrains. We show that the proposed interference awareness mechanism of IPBM, in which the transmission power of the units is increased at certain periods, significantly reduces the packet loss caused by the interference problem. Moreover, IPBM achieves an important amount of increase in the link reliability as well as in goodput with the least power consumption among the evaluated solutions. The mobility support feature of IPBM makes the protocol applicable not only to large and dense but also to highly dynamic MANETs. Besides, IPBM can properly work alongside the deployed main data communication protocol, since it provides valuable network information to be manipulated. Simulation results under both static and dynamic topologies confirm that adopting the IPBM protocol in the intended MANET scenarios significantly increases the reliability and goodput as well as the energy efficiency.

“…Nevertheless, these works are suitable for Vehicular ad Hoc Network (VANET) environments and do not properly address the deafness problem which is very relevant in MANET. In [28] we introduce a predictive location mechanism that also provides for a frame scheduler with priority in order to reduce the handoff problem. However, in this case, the energy consumption of nodes is not considered.…”

The use of Smart Antenna Systems (SAS) in pervasive environments such the Mobile Ad hoc Networks (MANET) has been promoted as the best choice to improve Spatial Division Multiple Access (SDMA) and throughput. Although directional communications are expected to provide great advantages in terms of network performance, directional MAC (Medium Access Control) protocols introduce several issues. One of the most known problems in this context is represented by the fact that, attempting to solve or at least mitigate the problems introduced by these kinds of antennas especially at MAC layer, a large amount of energy consumption is achieved ; for example, due to excessive retransmissions introduced by very frequently issue such as deafness and handoff. The expedients proposed in order to reduce these drawbacks attempting to limit beamforming time of nodes in cooperation with a Round-Robin scheduling, can grant high performance in terms of fairness and throughput. However the overall energy consumption in the network is not efficent due to the static approach. In view of this, we propose an Adaptive Beamforming Time with Round-Robin MAC providing for a dynamic assignment of the beamforming time with the purpose to limit the waste of energy of nodes.

“…For example, in [33], the authors attempt to limit the handoff problem through the use of an efficient beam control mechanism; a similar approach is proposed in [34] in which handoff is reduced using a predictive location model that is able to estimate future movements of nodes. Similarly, the work [35] presents a predictive location algorithm using in-frame priority scheduling in order to reduce the handoff.…”

However, the overall energy distribution in the network is not efficient due to static approach. In view of this, we propose adaptive beamforming time with round-robin MAC providing a dynamic assignment of the beamforming time with the aim to limit the waste of energy of nodes. The proposed approach provides benefits in terms of energy consumption distribution among nodes in sectorized antennas environments and, simultaneously, improves MAC packet performance.
