Transport protocols are traditionally designed and implemented as a monolithic entity. As a result, it is extremely di cult for researchers to modify a small portion of it and evaluate it independently. This barrier encourages the re-use of existing transport protocols out of convenience even when performance is sub-optimal. In this paper, we explore the challenges of separating di erent transp...

A common application of unattended sensor networks (WSN) is low data rate streaming from many scattered sensors to one or more sink nodes, where packet error rate per link vary within 1-70% and path length could be up to tens of hops. To cope with the stringent requirement of battery lifetime, a new notion of statistically reliable transport protocol is introduced and the energy-efficiency of a...

Transmission Control Protocol (TCP) can handle packet losses by retransmitting them when the corresponding acknowledgement (ACK) packets are not received within a certain time interval. This time interval is referred to as retransmission timeout (RTO) and setting its value is critical to reduce the packet delay in Smart Grid AdvancedMetering Infrastructure (AMI) networks. In this paper, we prop...

This work provides the specification of a PHY and MAC layers simulator that allows to evaluate the IEEE 802.11e service quality. A detailed state transition diagram is presented along with a description of the related attributes and methods, an identification of the associated events and input variables, and a description of functions for events. For validation purposes, results of the goodput ...

In this paper we analyze the performance of multiple relay channels when multiple antennas are deployed only at relays. We apply two antenna diversity techniques at relays, namely maximum ratio combining (MRC) on receive and transmit beamforming (TB). We show that with K relays the network can be decomposed into K diversity channels each with a different channel gain, and that the signals can b...
