Topic: A progressively reliable image transport protocol for wireless
sensor networks.

Abstract:
Images are extensively used in Wireless Sensor Networks (WSN) for
surveillance and object monitoring. The transmission of image data
constitutes a significant portion of traffic over the networks. Given
the inherent differences of WSN from wired networks, such as high
probability of non-congestion related packet loss, very low bandwidth
and limited processing power, the traditional transport protocol for
transferring images -- the Transport Control Protocol (TCP) is not
satisfiable any more mainly for two reasons. First, TCP regards all
packet loss as congestion related and invokes its congestion control
immediately, which is not necessarily the case for WSN. Second, the
in-order packet delivery of TCP prevents a progressive display of the
image and results in long idle time for the user in a loss-prone
network. In this thesis, we propose a progressively reliable
image transport protocol (PITP), which is implemented to allow
out-of-order delivery of packets and to display the image smoothly with
incremental quality with the support of progressive JPEG. We conduct a
serial of experiments and simulate them in NS-2 to evaluate the
performance of PITP. According to the results, PITP is believed to be
better tailored for image transmission over WSN.
