Recent research in communication moves towards cyber space with modern applications such as multimedia surveillance, smart autonomous traffic control, advanced health care monitoring, industrial automation, and continuous remote environmental and structural monitoring. Such applications are extensively generates multimedia information and converse through Wireless Multimedia Sensor Networks (WMSNs). Path selection plays vital role in transmitting the multimedia data over wireless networks. Single path selection incurs routing failure due to the energy hole because of power shortage and traffic congestion. Due to energy hole in any particular node the packet gets dropped in the route from source to destination. The multipath routing algorithm selects more than one path to increase the rate of the packet delivery than the single path routing. The prediction of energy deficiency in sensor nodes is becoming over head in WSMNs. In order to improve the packet delivery and performance of the network, in this paper a Priority Based Multipath Routing Algorithm (PBMRA) is proposed. It consists of three modules: The Neighbourhood Selection identifies the neighbours; Multipath Construction constructs multiple paths from the indentified neighbours; and Priority Selection selects the high energized routes based on the priority of node attributes such as liveliness, path delay and hop count. The proposed algorithm is experimentally compared with other existing algorithms such as AODV, DSR, DSDV and OLSR. The experimental results show that the PBMRA algorithm increases the overall throughput, packet received rate and provides the reliable route than existing algorithms.

通过PBMR算法在多径无线多媒体传感器网络中进行QoS优化

通讯方面的最新研究通过多媒体监控，智能自主交通控制，高级医疗监控，工业自动化以及连续的远程环境和结构监控等现代应用程序向网络空间发展。此类应用广泛生成多媒体信息，并通过无线多媒体传感器网络（WMSN）进行交谈。路径选择在通过无线网络传输多媒体数据中起着至关重要的作用。由于电力短缺和交通拥堵，单向路径选择会因能量漏洞而导致路由失败。由于任何特定节点中的能量孔，数据包在从源到目的地的路由中丢失。与单路径路由相比，多路径路由算法选择一条以上的路径来提高数据包传递的速率。在WSMN中，传感器节点中能量不足的预测变得越来越困难。为了提高网络的数据包传递和性能，本文提出了一种基于优先级的多路径路由算法（PBMRA）。它由三个模块组成：邻居选择标识邻居。多路径构造从确定的邻居构造多条路径；“优先级选择”根据节点属性的优先级（例如活动性，路径延迟和跳数）选择高能量路由。将该算法与其他现有算法（如AODV，DSR，DSDV和OLSR）进行了实验比较。实验结果表明，与现有算法相比，PBMRA算法提高了整体吞吐量，数据包接收速率，并提供了可靠的路由。
