Abstract

Efficient protection techniques for multimedia data transfer over Wireless Sensor Network (WSN) are very essential issues. In noisy Wireless Multimedia Sensor Networks (WMSN) Quality of Service (QoS) is a challenging task due to bandwidth and limited energy, and unpredictable channel conditions. Therefore, Forward Error Correction (FEC), a class of channel coding has been widely used in WSN. Nevertheless, the bulky size of multimedia data makes it more difficult to be transported over the noisy multi-hop wireless network. Moreover, the efficiency of FEC drops as the number of hops increases. In this paper, an optimized protection technique based on network coding and rateless code has been proposed to enhance the throughput and reduce overhead during data transfer in WMSN. The performance of NCP-OPR is enhanced via Optimal Network Path Model (ONPM) where the best available paths are optimally selected using Particle Swarm Optimization (PSO). In conjunction with the proposed protection scheme, the proposed ONPM is intended for limited power WSN by optimally distributing the power usage among the network paths so that the throughput can be improved.
优化网络编码路径,增强无线多媒体传感器网络的编码保护
无线传感器网络中多媒体数据传输的有效保护技术是一个非常关键的问题。在有噪声的无线多媒体传感器网络(WMSN)中,由于带宽和能量的限制以及信道条件的不可预测,服务质量(QoS)是一项具有挑战性的任务。因此,前向纠错(FEC)这一类信道编码被广泛应用于无线传感器网络。然而,多媒体数据的庞大尺寸使得在多跳噪声无线网络上传输变得更加困难。此外,FEC的效率随着跳数的增加而下降。本文提出了一种基于网络编码和无速率码的优化保护技术,以提高WMSN的吞吐量,降低数据传输的开销。通过最优网络路径模型(ONPM)提高NCP-OPR的性能,其中使用粒子群优化(PSO)最优选择最佳可用路径。结合所提出的保护方案,所提出的ONPM旨在通过在网络路径之间优化分配功率,从而提高吞吐量,从而用于有限功率的WSN。
