An Anycast Communication Model for Opportunistic Network

Opportunistic Network is a special kind of Challenged Networks in which the path between the source and the destination is not persistent in all times. Any cast is a new "one-to-one-of-many" communication method. Although some any cast schemes have been designed and proposed for opportunistic networks, few of them have discussed how any cast was carried out in detail. In this paper, we present an entire any cast communication model (ACM) to describe any cast communication processes and activities. Firstly, we describe the environment of opportunistic networks. Secondly, we propose the framework, components and basic activities of the any cast communication model. Lastly, we analyze and verify the availability of ACM based on a colored Petri Nets (CPN).
