An alternative model, called peer-to-peer networking, allows all the devices on a network to function as either a server or client on an as-needed basis. [12] In contrast to large data centers or rack servers, the mobile server is designed for on-the-road or ad hoc deployment into emergency, disaster or temporary environments where traditional servers are not feasible due to their power requirements, size, and deployment time. This is in contrast with peer-to-peer model in which the relationship is on-demand reciprocation. The following table shows several scenarios in which a server is used.
