M-UDP

Abstract

In this paper we present our implementation of a modified UDP protocol appropriate for the mobile networking environment. Our protocol, like UDP, does not guarantee reliable delivery of datagrams. However, unlike UDP, it does ensure that the number of lost datagrams is kept small. In this paper we discuss our implementation of M-UDP (in NetBSD) and compare its performance against that of UDP in an experimental mobile network that is currently under development at the University of South Carolina.
