A Smart Multi-Hop Hierarchical Routing Protocol for Efficient Video Communication Over Wireless Multimedia Sensor Networks

For smart applications, nodes in Multimedia Wireless Sensor Networks (MWSNs) have to take decisions based on sensed scalar physical measurements. A routing protocol must provide the multimedia delivery with quality level support and be energy-efficient for large-scale networks. With this goal in mind, this paper proposes a smart Multi-hop hierarchical routing protocol for Efficient VIdeo communication (MEVI). MEVI combines an opportunistic scheme to create clusters, a cross-layer solution to select routes based on network conditions, and a smart solution to trigger multimedia transmission according to sensed data.
