A scalable model for channel access protocols in multihop ad hoc networks
A new modeling framework is introduced for the analytical study of medium access control (MAC) protocols operating in multihop ad hoc networks. The model takes into account the eļ...

Performance Evaluation of Modified IEEE 802.11 MAC for Multi-Channel Multi-Hop Ad Hoc Network
In this paper, the IEEE 802.11 multiple access control protocol was modified for use in multi-channel, multi-hop ad hoc network, through the use of a new channel-status indicator....

The effects of shadow-fading on QoS-aware routing and admission control protocols designed for multi-hop MANETs
ā€”Providing quality-of-service (QoS) assurances in a mobile ad hoc network (MANET) is difļ¬cult due to node mobility, contention for channel access, a lack of centralised coordin...

Hybrid Channel Access Scheduling in Ad Hoc Networks
We present the hybrid activation multiple access (HAMA) protocol for ad hoc networks. Unlike previous channel access scheduling protocols that activate either nodes or links only,...

Computational Time-Division and Code-Division Channel Access Scheduling in Ad Hoc Networks
Using two-hop neighborhood information, we present the hybrid activation multiple access (HAMA) protocol for time-division channel access scheduling in ad hoc networks with omni-di...
