This paper presents and evaluates Hash-Based DSR, an extension of the DSR protocol. This protocol reduces the per-packet control overhead of DSR by compressing the source-route with a Bloom filter. Simulations on large networks show that HB-DSR increases the network capacity by a factor of up to 15. HB-DSR is an attractive alternative to DSR for large ad-hoc networks. Another important property of HB-DSR is that, as opposed to DSR, its performan- ce is similar for IPv4 and IPv6. While IPv6 large addresses is a show-stopper for DSR, we show by simulations that HB-DSR performs as well for both IP versions. This is important contribution considering the growing interest of the wireless network community for IPv6.
