Vector switching scheme (VSS) for source routing protocol of MANET
Zhiwei Wang, Mangui Liang, J.X. Zhang · 2008
A Mobile Ad hoc NETwork (MANET) is a group of mobile nodes which cooperate in forwarding packets in a multi-hop fashion without any centralized administration. One of its key challenges is routing. Many protocols for MANETs have been proposed and the protocols can be classified as proactive and on demand protocols. The later protocols without periodic updates scale better. Dynamic Source Routing (DSR) protocol is a popular on demand protocol of MANET. It uses explicit routing in data packet header to lead packet to destination. This allows other nodes forwarding any of these packets to cache this information easily for future use. However, this protocol has a high overhead of packet header. In this paper, we present a new packet forwarding scheme, Vector Switching Scheme which employs Vector Address (VA) to replace source route in packets, for source routing. The proposed scheme reduces overhead of packet header in source and enhances packet transfer performance.
