Multi-path Transmission Algorithm for End-to-End Seamless Handover across Heterogeneous Wireless Access Networks

In mobile networks, new technologies are needed to enable mobile hosts to move across various kinds of wireless access networks. In the past, many researchers have studied handover in IP networks. In almost all cases, special network devices are needed to maintain the host’s mobility. However, in these technologies, mobile hosts cannot move across different wireless access networks without closing the connection and degrading the goodput. To overcome these, we propose here a multi-path transmission algorithm for end-to-end seamless handover. The main purpose of this algorithm is to improve the goodput during handover by sending the same packets along multiple paths, reducing unnecessary consumption of network resources. We evaluate our algorithm through simulations and show that mobile hosts gain a better goodput.
