TCP- Transmission Control Protocol providesconnection oriented, reliable, process to process communication.TCP was initially implemented with wired networks where themain cause of packet drops is congestion rather than channelissues like interference, noise, attenuation etc. when TCP isimplemented with wireless networks, a significant amount ofperformance degradation can be noticed specially because ofTCP’s misinterpretation between congestion losses and any otherlosses. Various schemes have been proposed to differentiatevarious losses to improve overall performance. These approachesare broadly classified into two categories, cross layeredapproaches and layered approaches. In cross layered approaches,lower layer provides feedback – decision making information tothe TCP to act accordingly. In layered approaches, TCP itselfdecides and acts without any feedback – decision makinginformation from the lower layers. This paper focuses on layeredapproaches to improve TCP’s performance. Approaches areclassified into three categories for route failures, channel lossesand channel contention issues.
