Real-time applications over wireless networks often suffers from jitter, delay and packet loss. The traditional techniques for error control are FEC (Forward Error Correction) and ARQ (Automatic Repeat Request). In this paper a hybrid FEC/ARQ mechanisms with limiting the slots number between the loss of the last retransmission of the original block n and the reception of block n + φ is analyzed in...
With growth of Internet and wireless IP network, multimedia systems can be accessed from any-where and anytime. However, efficient real-time services are open and challenging research problem. To implement real-time services such as VoIP over wireless access network, IP header compression scheme can be used for saving bandwidth. Enhanced compressed RTP (ECRTP) has been used for lossy link and high...
