This paper presents several distributed algorithms that cause a token to continually circulate
through all the nodes of a mobile ad hoc network. An important application of such …

Providing a reliable group communication in a mobile ad hoc network (MANET) is a
challenging task. The dynamic nature of this network makes it highly unreliable. Moreover …
