Abstract

To support the real-time transport protocol (RTP) over wireless networks is essential for transporting real-time data streams. However, the RTP introduces significant header overheads, which cannot be adequately employed in wireless networks. An enhanced compressed RTP (ECRTP) with mobility support for wireless networks is presented, which is based on the, compressed RTP (CRTP). The ECRTP uses the local-link retransmission mechanism to recover transmission errors over wireless links. The simulation results show that ECRTP consumes insignificant network bandwidth and maximizes successfully received packets compared with RTP and CRTP in an error-prone and bandwidth limited wireless network. Consequently, the playback quality of real-time data streams is improved for wireless networks
