Analysis of TCP-Reno and TCP-Vegas over AOMDV routing protocol for mobile ad hoc network

摘要

A mobile ad hoc network eliminates the complexity of infrastructure configuration and allows wireless devices to communicate with each other on the fly. It does not rely on a base station to coordinate the flow of messages in the network. A primary challenge is to provide each device to maintain the information to properly route traffics using a routing protocol and conveying data packets efficiently using a transport protocol. Many routing protocols and transport protocols are currently being developed to handle the wireless environment efficiently. In this paper, we investigate the performance differences of TCP-Reno and TCP-Vegas utilizing an AOMDV routing protocol. Although TCP-Vegas provides a better throughput than TCP-Reno in a static environment, it suffers performance degradation in a mobile environment, where packet loss rate, throughput, normalized routing load and average delay are measured as performance metrics, as well as discussed by describing strengths and weaknesses of TCP-Reno and TCP-Vegas.
