The emerging heterogeneous network environments and the wide widespread deploying Internet applications introduce an interesting requirement: how to use any type of Internet application with any type of device, on any type of network. To this end, previous researchers have introduced concepts of adaptive network architectures. They address problems associated with the heterogeneity by using distributed entities to adapt the system and the applications to the current operating conditions. However, a major problem of these architectures is the discovery of the entities that are used for adaptation. Most proposed discovery mechanisms mainly concentrate on one administrative domain, or a single network operator. To solve this problem, we introduce an alternative enhancement feature for an existing service discovery architecture using peer-to-peer protocol. We also evaluate our architecture by comparison with other potential solutions. Finally, we confirm the viability of our proposal through simulation.
