“…Fig. 8 presents the percentage of sensor nodes network connectivity, traveling at 2 m/s, for the three batches under evaluation (6,30, and 50 sensor nodes). As can be observed, even when the number of sensor nodes increases, Hand4MAC can ensure connectivity above 93%.…”

“…The monitoring tasks of patients' health parameters can be autonomous and automated using small sensor nodes attached to their bodies. Besides, these sensor nodes can be wireless, connected to a network infrastructure and so make them accessible anywhere, at any time over the Internet [6]. To promote the patients' comfort, the sensor nodes have to be tiny and light.…”

Abstract:This work proposes an error-resilient video coding scheme for improving the ecosystem of Wireless Visual Sensor Network (WVSN). In order to optimize the video information communication over WVSN, this work first provides a discussion on ecology technology model of video transmission in the WVSNs. And then proposes a Distributed Video Parallel Coding scheme, which make use of the correlation of video information in the decoder side, to cope with the loss of video data over wireless error-prone channel. Specifically, this work proposes a Partition Irregular Repeat Accumulate codec, which exhibits better error resilience performance and obtain the same compression ratio with traditional video coding method. The experimental results indicate that the performance of the proposed Distributed Video Parallel Coding scheme is promising and can better optimize the ecosystem of video communication over WVSN.
