Survey of QoS Routing Protocols in Wireless Multimedia Sensor Networks

Abstract

The emergence of Wireless Multimedia Sensor Networks (WMSNs) has stimulated the refocusing of research from conventional scalar Wireless Sensor Networks (WSNs) to WMSNs. Currently, because of their prevalence WMSNs are used in different applications. Due to the unique features of WMSNs, fulfilling Quality of Service (QoS) requirements for a variety of applications is the challenge. QoS routing is a backbone of WMSNs and plays a vital role in satisfying QoS requirements. The performance of QoS routing depends upon the selection of an optimal path or paths. Path selection is based on evaluation of a cost function using various routing metrics. A careful blend of such metrics in a routing cost function guarantees a committed level of QoS. This survey uses number of routing metrics as criteria for categorizing state-of-the-art QoS WMSNs routing techniques. In addition, open issues and future research directions to further develop efficient routing protocols to guarantee QoS are discussed.

Routing in Wireless Multimedia Sensor Networks: A Survey of Existing Protocols and Open Research Issues

“…WMSN has got huge attention in the past few years, but still it is in evolving stage [13]. Research papers [1,2,13] have summed up current issues in QoS and energy efficient routing for WSNs and WMSNs. This paper has already mentioned various design requirements.…”

“…They performed simulation to analyse various metrics and finally summarized the simulation results. Aswale and Ghorpade [13] surveyed state-of-the-art QoS routing protocols and summarized their analysis in table, including each protocol's strengths and weaknesses, and finally summarized various issues in routing in WMSNs. At the end, previous works related to ours are condensed in Table 1.…”

Image Transmission Model with Quality of Service and Energy Economy in Wireless Multimedia Sensor Network

“…In general, a criterion is a system or standard of measurement defined as a parameter for quantitatively assessing a method, event, and entity by using special procedures to perform measurements [14].…”

“…Image compression is the optimal solution to solve these problems simultaneously [3][4][5][6] while it saving a lot of energy, by sending a small amount of information (compressed image) in the circumstances of the comfortable Qos of the network in terms of flow of information, and no dropped packets in optimal time. The previous scenario is better than the second, which involves sending a very large amount of information (original image), which consumes more energy in unsatisfactory network conditions due to large information flows occupying bandwidth and dropping a high number of packets in a long time.…”

Fault-resilient and QoS centric dynamic network sensitive routing protocol for mobile-WSNs

“…In practice, this process might undergo single hop transmission as well as multiple hop transmission. Considering application specific scenarios, majority of WSNs applications demand scalar, data driven and data centric, reliable and delay sensitive transmission to avail QoS (Aswale and Ghorpade, 2015;Ehsan and Hamdaoui, 2011).…”
