  7. Abstract:
  8. The quality of service in Wireless Multimedia Sensor Networks (WMSNs) is related to packet loss rate. Recently dierent studies have been done on developing ecient protocols in the transport layer for controlling packet loss in WMSNs. However, all of these protocols are independent of the characteristics of the multimedia content. In this thesis, a novel transport layer protocol, called User Datagram Dispatcher Protocol (UDDP), is proposed to minimize the packet loss ratio in WMSNs by considering trac characteristics, the inter-arrival pattern of packets and packet priority. UDDP is a new cross-layer transport layer that uses information of MAC and application layers to distribute packet arrivals in a GOP. Also in this thesis a Content-Aware Congestion Control protocol (CACC) is proposed. The CACC protocol is a congestion control protocol for WMSNs that work with the UDDP transport layer. CACC along with UDDP result in better video quality in receiver side. The experimental results show that our protocols provide performance improvement in terms of high video quality, packet loss, energy conservation and delay compared to other protocols such as CCF and PCCP
