A Cross-layer and Multipath based Video Transmission Scheme for Wireless Multimedia Sensor Networks
The issue of video transmission for wireless multimedia sensor networks (WMSNs) was studied in this paper. Video applications were generally characterized by large data size and strong real-time requirement. However, nodes in WMSNs had limited resources and the quality of service for video applications was hard to ensure. This paper studied this problem and presented a cross-layer and multipath...

متن کاملDistributed Reservation Algorithms for Video Streaming over WiMedia UWB Networks
Ultra-wideband (UWB) technologies with higher data rates and lower transmission power over shorter ranges, have enabled a new set of applications in Wireless Personal Area Networks (WPANs). For example, UWB can offer data rates 50 to 500 times higher than the current WPAN technologies such as Bluetooth. This property makes UWB a primary candidate for indoor high-speed multimedia applications su...
متن کاملA Cross-layer Contention Based Synchronous MAC Protocol for Transmission Delay Reduction in Multi-Hop WSNs
Recently designed cross-layer contention based synchronous MAC protocols like the PRMAC protocol, for wireless sensor networks (WSNs) enable a node to schedule multi-hop transmission of multiple data packets in a cycle. However, these systems accommodate both the request-to-send data process and the confirmation-to-send data process in the same data transmission scheduling window (i.e. data win...
