Abstract-The requirements of multimedia underwater monitoring applications with heterogeneous traffic demands in terms of bandwidth and end-to-end reliability are considered in this article. To address these requirements, a new medium access control protocol named UMIMO-MAC is proposed. UMIMO-MAC is designed to i) adaptively leverage the tradeoff between multiplexing and diversity gain according to channel conditions and application requirements, ii) select suitable transmit power to reduce energy consumption, and iii) efficiently exploit the UW channel, minimizing the impact of the long propagation delay on the channel utilization efficiency.To achieve the objectives above, UMIMO-MAC is based on a two-way handshake protocol. Multiple access by simultaneous and co-located transmissions is achieved by using different pseudo-orthogonal spreading codes. An algorithm is proposed that, in a cross-layer fashion, jointly selects optimal transmit power and transmission mode through the cooperation of transmitter and receiver to achieve the desired level of reliability and data rate according to application needs and channel condition. Extensive simulation results show that UMIMO-MAC increases network throughput, decreases channel access delay, and decrease energy consumption compared with existing MAC protocols for UW-ASNs.Index Terms-Underwater acoustic sensor networks, Medium access control, Multiple input multiple output.

“…The Multiple-Input Multiple-Output (MIMO) technique has also been widely applied in wireless networks for mitigate fading effects and consequently enhance performances of the network [1][2][3]. Recent research on MIMO ad hoc networks has mainly focused on either mitigating fading of wireless links by exploiting spatial diversity [4][5][6] or improving the efficiency of networks by exploiting spatial multiplexing [7][8][9][10][11][12].…”

“…In particular, some new MAC protocols have also been proposed to create spatial multiplexing of MIMO transmissions [8][9][10][11][12]. Spatial multiplexing in a MIMO ad hoc network forms multiple links in a neighborhood for simultaneous data transmissions to improve the transmission efficiency of the network [7]. In [8] a multiple contention slots MAC protocol named Mitigating Interference using Multiple Antennas MAC (MIMA-MAC) has been proposed.…”

“…Medium access control (MAC) for complex wireless networks is an important area of research [1], [2], especially when including multiple antennas [3]- [5]. The transport capacity per node of wireless networks in many scenarios has been found to decrease with the number of nodes in a network [6], [7].…”

“…Our focus is on the use of antennas not just for directional diversity, but for throughput increase [11]. In [3] links are characterized as bottleneck and non-bottleneck links according to the amount of traffic required; the focus is on scheduling, rather than the PHY/MAC interaction. Antenna selection is used in a joint MACphysical layer coding scheme in [4]; one antenna at each transmitting node is used for transmission, and N for reception.…”

Abstract-We present medium access controllers (MAC) for ad-hoc networks which include uplink and downlink multi-user physical layer models as well as multiple antennas. We note the advantages of these MACs over those in the literature, including a multi-antenna version of the CSMA/CA protocol used in the distributed coordination function (DCF) mode of the IEEE 802.11 MAC. Specifically, our MAC is among the first to explicitly consider multi-user techniques in an ad-hoc network, which results in superior rate performance. We include interference and network topology in the design of our protocols. We characterize MAC controllers in terms of transport capacity, and present numerical results which show the benefit of multi-user techniques in the physical layer.
