Quality and Energy Aware Multipath Routing in Wireless Multimedia Sensor Networks

Abstract

In Wireless Multimedia Sensor Networks (WMSNs), the sensor nodes are capable of acquiring the multimedia information like wildlife tracking, traffic accidents as well scalar data. Because of these factors, the WMSNs have a bright future in both academic and industry circles. Multimedia applications, on the other hand, generate a lot of network traffic, which causes a lot of delay and wastes a lot of energy. In WMSNs, both network duration and quality of service are critical, hence an effective routing algorithm that can manage more data while simultaneously extending network lifetime is necessary. Towards this objective, in this paper, we proposes a Quality Aware Multipath Routing (QAMR) that selects multiple paths based on three reference metrics; they are Expected Transmission Count, Energy and Delay. For a given source and sink node, the QAMR constructs a composite metric by combining these three metrics and selects node disjoint multiple paths. Since the multiple paths with common nodes has less efficiency in data forwarding, we opt for node disjoint paths in which no two paths have one common node. On the proposed system QAMR model, extensive simulation tests are performed, and the outcomes are evaluated using a variety of metrics such as energy consumption, throughput, delay, and packet delivery ratio.
