Simulation Base Analysis of TCP Reno and TCP Westwood Over IEEE 802.11 Wireless Ad hoc Networks

Mobile ad hoc networking has been a fast growing research area for the last few years. The need for a network when there is no fixed infrastructure is no more limited to military and emergency applications; ad hoc networks can include private and public applications as well. In ad hoc networks, wireless mobile computing devices can perform critical network topology functions that are normally the responsibility of the routers within the Internet infrastructure. Although there are many kinds of protocols available today that are supported by fixed network infrastructure, they need adaptation before they can be useful in ad hoc networks no longer connected to the Internet infrastructure. In this paper, we have studied the performance of TCP Westwood as compared with TCP Reno, to investigate the possibility of implementation of TCP Westwood in wireless environment and so in IEEE 802.11 wireless ad hoc networks.
