Abstract:Manycast is a new "one-to-some-of-many" communication pattern. It is the general communication form of anycast and multicast. With manycast a client can contact several servers to increase reliability or a distributed service can disseminate the important information to more than one server throughout a MANET network. This paper describes the main issues with manycast and mechanisms proposed in the last a few years. It also discusses some possible optimizations by taking advantage of other related work and shows some applications that have already been deployed in practice.
