ABSTRACT

In this paper we survey issues and challenges in enhancing the survivability of mobile wireless networks, with particular emphasis on military requirements. Research focus on three key aspects can significantly enhance network survivability:

1. establishing and maintaining survivable topologies that strive to keep the network connected even under attack,
2. design for end- to-end communication in challenging environments in which the path from source to destination is not wholly available at any given instant of time,
3. the use of technology to enhance survivability such as adaptive networks and satellites.
