TECHNIQUES FOR LOSS RECOVERY IN WIRELESS NETWORKS BASED ON ACKNOWLEDGMENTS
Abstract
Wireless networks applications enabled the people to communicate, from any where in the globe. Performance of
reliable transmission control protocol (TCP) degrades in wireless networks due to its inability to detect and recover losses
due to unreliable nature of wireless network such as signal fading, low bandwidth, bit error rate etc. This results in low
utilization of available bandwidth, unnecessary retransmission and low throughput. We propose sender oriented loss
recovery technique (SOLRT) to detect and recover packets lost in network due to congestion and link error. Link error is
detected using timeout. SOLRT reduces congestion occurrence, retransmission and recovery time in chosen path by
predicting next transmission rate. To test the performance, we have simulated and analyzed the parameters retransmitted
packets, delay and recovery time. The performance of SOLRT is better as compared to explicit loss notification (ELN) even
under heavy traffic.
