“…In this section EQWSN framework will be compared to non-adaptive QPS, QPS+ [36], which uses static encoding parameters GL = 7 and Bf = 2 regardless wireless channel state, while EQWSN framework uses optimal GL and Bf parameters [13] depending on wireless channel state; in addition it apply packet, queue and path scheduling as explained in previous section. QPS-Scheme [14] applies packet, path and queue scheduling techniques, where queue priority scheduling is used at data link layer that uses 4 different queues to priotorize packets in round robin way. Finally, it uses path scheduling that route packets according to its type but without considering fair usage of battery through network.…”

“…In this work [14] a video transmission scheme which is content aware that schedules different video packets over different paths, so that high priority packets are transmitted through high quality paths. Source nodes send control messages periodically to sink node to exchange state of each routing path.…”

“…It is based on AOMDV [37] multipath routing protocol which routes packets regardless its type, it uses optimal number of hops for routing packets; while EQWSN routing protocol which is a modified version of [14] that 4to rank each path based on network energy status, available buffer, number of hops, lost packet. EQWSN preserves power consumed in network by choosing paths with less power consumption until network reach the energy threshold value, and then it favors paths with better energy reserve regardless power consumed.…”

Wireless Multimedia Sensor Networks (WMSNs), is a network of sensors, which are limited in terms of memory, computing, bandwidth, and battery lifetime. Multimedia transmission over WSN requires certain QoS guarantees such as huge amount of bandwidth, strict delay and lower loss ratio that makes transmitting multimedia is a complicated task. However, adopting cross-layer approach in WMSNs improves quality of service of WSN under different environmental conditions. In this work, an energy efficient and QoS aware framework for transmitting multimedia content over WSN (EQWSN) is presented, where packet, queue and path scheduling were introduced. It adapts the application layer parameter of video encoder to current wireless channel state, and drops less important packets in case of network congestion according to packet type. Finally, the path scheduling differentiates packets types/priority and route them through different paths with different QoS considering network lifetime. Simulation results show that the new scheme EQWSN transmits video quality with QoS guarantees in addition to prolonging network lifetime.

“…Normally in videos the frame rate is 30 frames per second. In these frames different priorities are assigned to different frames [12]. The three different priority frames are, I-frames (Intra-Coded frames), P-frames (Predictive frames) and B-frames (Bi-predictive frames).…”

<p class="Default">Simulating wireless sensor networks; there implementation and evaluation, require the use of a discrete event simulator. Omnet++ is quite a powerful simulator which supports concise and easy modeling of wired as well as wireless sensors environment. Scenarios involving multimedia transmissions with characteristics of video quality control and evaluation must be computed on the basis of Quality of Experience which relies on user’s perception to maintain the video quality. For the multimedia growth and awareness of future WMSNs, it is quite necessary that the performance should be tested for different types of radio models. So varying the radio parameters may allow for the optimization and improvement of the video quality. In this paper we have provided a test bench for the easy evaluation and optimization of the performance of WMSNs using different radio models. The performance is evaluated based on the QoE metrics; i.e. PSNR(Peak Signal-to-Noise ratio) and MoS(Mean Opinion Score), which depend on user’s perception to maintain the video quality.</p>
