Abstract: We present the Hybrid Activation Multiple Access scheduling protocol (HAMA) for wireless ad hoc networks. Unlike previous channel access scheduling protocols that activate either nodes or links only, HAMA is a node-activation oriented channel access scheduling protocol that also maximizes the chance of link activations. According to HAMA, the only required information for scheduling channel access at each node is the identifiers of neighbors within two hops. Using this neighborhood information, multiple winners for channel access are elected in each contention context, such as a time slot in a frequency band or a spreading code. Except for time slot synchronization and neighbor updates on the two-hop neighborhood changes, HAMA dedicates the bandwidth completely to data communication. The delay and throughput characteristics of HAMA are analyzed, and its performance is compared with pure node activation based scheduling protocols by simulations.

An Integrated Cluster-Based Multi-Channel MAC Protocol for Mobile Ad Hoc Networks
TL;DR: This paper proposes a novel joint clustering and multi-channel medium access control (MAC) protocol for mobile ad hoc networks, based on a scalable two-phase coding scheme, which substantially reduces the control overhead of code assignment in a code division multiple access (CDMA) based multi- channel MAC protocol while simultaneously combating the hidden terminal problem.

TL;DR: Through integration of antenna selection and control into a time-division MAC scheduling process, it is argued that through such integration it is possible to achieve greater spatial reuse and interference mitigation than by solving the two problems separately.

- 16 Nov 2004
TL;DR: A novel location-aware multi-channel MAC protocol is presented for a large-scale dense MANETs based on a scalable two-phase coding scheme, where the first- phase code is used for differentiating adjacent cells and the second-phase code is employed for distinguishing nodes in one specific cell.

TL;DR: This analysis shows that using carrier sensing as an integral part of the floor acquisition strategy provides the benefits of MACA in the presence of hidden terminals, and can provide a throughput comparable to, or better than, that of non-persistent CSMA when no hidden terminals exist.
