ABSTRACT
This chapter focuses mainly on wireless multimedia sensor networks (WMSNs); compares the existing cross-layer protocols for WMSNs that join adjacent or nonadjacent layers; and classifies them based on the routing techniques into three categories: multichannel routing, single path routing, and multipath routing. The sensor nodes have the ability to sense the environment, process the data locally, and communicate giving birth to wireless sensor networks (WSNs) by coordinating the effort of a large number of deployed sensor nodes. The architecture of WMSNs consists of multiple components, and each component provides different functions. Many researchers produced different designs and protocols for cross-layer architecture to increase data gathering from WMSNs nodes to the sink, reduce the latency, increase the bandwidth, and reduce the energy consumptions. WMSNs are useful in many applications, especially in surveillance to track objects and take appropriate actions, traffic avoidance and control systems to monitor the traffic to avoid congestion, advanced health care delivery, and smart homes.
