Distributed cache updating using dynamic source routing protocol

This document does not specifically address security concerns. IEEE Personal Communications, 3(1):34--42, February 1996.

Other protocols can make use of these protocol numbers as nodes that support them will processes any included destination options or routing headers according to the normal IPv6 semantics. Protocols for adaptive wireless and mobile networking.

Since a Route Error packet names both ends of the hop that is no longer valid, any of the nodes receiving the error packet may update their Route Caches to reflect the fact that the two nodes indicated in the packet can no longer directly communicate.

For each such route found, the route is effectively truncated at this hop. A node receiving a Route Error packet simply searches its Route Cache for any routes using this hop. In mission-oriented environments where all the nodes participating in the DSR protocol share a common goal that motivates their participation in the protocol, the communications between the nodes can be encrypted at the physical channel or link layer to prevent attack by outsiders. In Mobile Computing, edited by Tomasz Imielinski and Hank Korth, chapter 5, pages 153--181. This document does assume that all nodes participating in the DSR protocol do so in good faith and with out malicious intent to corrupt the routing ability of the network. Dynamic source routing in ad hoc wireless networks.
