Abstract-- The Internet Engineering Task Force has developed
Mobile IP to handle mobility of Internet hosts at the network
layer. Mobile IP, however, suffers from a number of drawbacks
such as high handover latency, packet loss, and conflict with
network security solutions. In this paper, we describe and
evaluate the performance of SIGMA, a Seamless IP diversity based
Generalized Mobility Architecture. SIGMA utilizes IP diversity to
achieve a seamless handover of a mobile host, and is designed to
solve many of the drawbacks of Mobile IP. Various aspects of the
performance of SIGMA and Mobile IPv6 enhancements have been
compared. Criteria for performance evaluation include handover
latency, packet loss, throughput, and network friendliness.
