TLDR
The performance investigation reveals that an IEEE 802.11 network may be able to carry traffic with time-bounded requirements using the point coordination function, however, the findings suggest that packetized voice traffic must be handled in conjunction with an echo canceler.Abstract:
The draft IEEE 802.11 wireless local area network (WLAN) specification is approaching completion. In this article, the IEEE 802.11 protocol is explained, with particular emphasis on the medium access control sublayer. Performance results are provided for packetized data and a combination of packetized data and voice over the WLAN. Our performance investigation reveals that an IEEE 802.11 network may be able to carry traffic with time-bounded requirements using the point coordination function. However, our findings suggest that packetized voice traffic must be handled in conjunction with an echo canceler.read more

Mitigating routing misbehavior in mobile ad hoc networks
TL;DR: Two techniques that improve throughput in an ad hoc network in the presence of nodes that agree to forward packets but fail to do so are described, using a watchdog that identifies misbehaving nodes and a pathrater that helps routing protocols avoid these nodes.

Dynamic tuning of the IEEE 802.11 protocol to achieve a theoretical throughput limit
TL;DR: A distributed algorithm is proposed that enables each station to tune its backoff algorithm at run-time and indicates that the capacity of the enhanced protocol is very close to the theoretical upper bound in all the configurations analyzed.

Z-MAC: a hybrid MAC for wireless sensor networks
TL;DR: Z-MAC is a hybrid MAC protocol for wireless sensor networks that combines the strengths of TDMA and CSMA while offsetting their weaknesses and achieves high channel utilization under high contention and reduces collision among two-hop neighbors at a low cost.

Capacity of a burst-noise channel
TL;DR: The capacity C of the model channel exceeds the capacity C(sym. bin.) of a memoryless symmetric binary channel with the same error probability; however, the difference is slight for some values of h, p, P; then, time-division encoding schemes may be fairly efficient.

A model for generating on-off speech patterns in two-way conversation
TL;DR: A model that generates on-off speech patterns representative of those in experimental two-way telephone conversations that yields good fits to all events except “speech before interruption;” when an interruption occurs, a model speaker tends to interrupt the other's talkspurt later than a real speaker does.
