Abstract A Spontaneous Area Network (SPAN) is formed by mobile and fixed nodes using
wireless transmission links between nodes, usually in a nearby geographical area.
Applications allow users to create, join, leave, and manage SPANs and groups in a SPAN.
Automatic procedures allow nodes to join other SPANs. Transmission power of the wireless
network interface is dynamic, varying depending on battery level, type of information to
transmit, state and topology of the network. A delay tolerant object layer abstraction creates …
