Multimedia Internet of Things: A Comprehensive Survey <s> D. MULTICAST AND HOP-COUNT BASED ROUTING <s> The vision of wireless multimedia sensor networks (WMSNs) nowadays is to afford real-time multimedia applications using the pervasive wireless sensors around us. This necessitates strict QoS conditions, which have led to new emerging challenges in terms of data delivery in the Internet of Things era. Accordingly, multipath routing protocols with multi-constraints are recommended in WMSNs. In this article, a comprehensive overview of both best effort and real-time multipath routing protocols for WMSNs is performed. The results of our investigations, with regard to design issues affecting the development of strategic multipath routing mechanisms that can support multimedia data exchange over a WMSN infrastructure are presented and discussed from the network design perceptions. <s> BIB001 </s> Multimedia Internet of Things: A Comprehensive Survey <s> D. MULTICAST AND HOP-COUNT BASED ROUTING <s> The vision of wireless multimedia sensor networks (WMSNs) is to provide real-time multimedia applications using wireless sensors deployed for long-term usage. Quality of service assurances for both best effort data and real-time multimedia applications introduced new challenges in prioritizing multipath routing protocols in WMSNs. Multipath routing approaches with multiple constraints have received considerable research interest. In this paper, a comprehensive survey of both best effort data and real-time multipath routing protocols for WMSNs is presented. Results of a preliminary investigation into design issues affecting the development of strategic multipath routing protocols that support multimedia data in WMSNs are also presented and discussed from the network application perspective. <s> BIB002
Routing protocols for multimedia bandwidth-hungry and real-time applications of M-IoT have been designed based on multicast and hop-count metric BIB001 . A detailed survey on multipath routing protocols of M-IoT to ensure QoS parameters has been presented in BIB002 . Below-mentioned are few studies in the context of multicast and multi-hop routing protocols of M-IoT.
