Survivability strategies in multihop wireless networks [Accepted From Open Call]

Survivability is an important network characteristic that provides a certain level of data delivery guarantees. The degree of survivability is usually governed by the data transfer mechanism or protocol that delivers data from source to destination. In this article we survey and discuss a variety of survivability issues, challenges, and mechanisms in multihop wireless networks. Unlike some previous surveys, we do not focus only on multipath routing techniques. We try to cover a broader spectrum of survivability techniques in the literature. Moreover, we discuss new directions in survivability that use the network coding technique in order to achieve a better degree of scalability, which is usually an issue in most survivability techniques, especially in wireless networks.
