GloMoSim: A Scalable Network Simulation Environment
A scalable simulation environment called GloMoSim (for Global Mobile Information System Simulator) is described that effectively utilizes parallel execution to reduce the simulation time of detailed high-fidelity models of large communication networks.
MAC reliable broadcast in ad hoc networks
A novel MAC protocol, broadcast medium window (BMW) that reliably delivers broadcast data is proposed that combines RTS, clear-to-send, and acknowledgement control frames.
Random access MAC for efficient broadcast support in ad hoc networks
A random access MAC protocol, broadcast support multiple access (BSMA) is proposed, which improves the broadcast reliability in ad hoc networks.

This paper provides new insight into two critical problems of TCP over wireless multi-hop, the conflict between data packets and ACKs, which causes TCP performance to degrade for window sizes greater than 1 packet and the interaction between MAC and TCP layer backoff timers which causes severe unfairness and capture conditions.

The results show that ReACT is the best performer in terms of reliability and the effect of ReACT’s local recovery mechanism which quickly corrects error- and path breakage induced losses and thus manages to prevent the source from reducing its rate unnecessarily, thus achieving significant throughput improvement with lower overhead when compared to the strictly end-to-end protocol.
Effects of Ad Hoc MAC Layer Medium Access Mechanisms under TCP
In this paper, several popular, contemporary, wireless, random access MAC protocols are surveyed and the effects behind the design choices of these protocols are determined.
Fair Sharing of MAC under TCP in Wireless Ad Hoc Networks
Using simulation, this study provides new insights into the interactions between TCP and various MAC layer protocols, including CSMA, FAMA and 802.11, and addresses the issue of fair sharing of MAC with multiple TCP flows.
