Multimedia Transmission over Wireless Sensor Networks

2011
This chapter presents an overview of multimedia information transmission over Wireless Sensor Networks (WSNs). These WSNs have evolved since the 1980s and their evolution can be divided into three generations. Wireless Multimedia Sensor Networks (WMSNs) have become viable in recent years with the availability of inexpensive video cameras, increase in ...

Efficient multimedia transmission in wireless sensor networks

2012 International Symposium on Intelligent Signal Processing and Communications Systems, 2012
For Wireless Multimedia Sensor Networks (WMSN), how to increase the throughput in constrained environments has become the main challenge. Multipath routing is a promising solution because it can improve the channel utilization rate, reduce transmission delay and balance the transmission load. To pursue high efficiency for a multipath routing scheme, we
