Wireless TCP

Posted by OurTech Team | Friday, October 15, 2010 | Category: |

 TCP is designed for wired networks to provide reliable delivery by using congestion control and error control mechanisms. However, the use of TCP in wireless networks exposes several problems because TCP is suggested for traditional wired networks and doesn't reflect the characteristics of wireless networks; First, the error rates of wireless networks are much higher than those experienced over wired networks. Second, a host frequently changes its location in wireless networks. These characteristics of wireless network contribute to severe degradation of TCP performance because TCP responds to all losses by invoking congestion control and avoidance algorithms. To solve these problems, several issues should be addressed in wireless networks: 

�� Limited Bandwidth 
�� Long Round Trip Time 
�� Random Losses 
�� User Mobility 
�� Short Flows
