Today's internetwork technology has been extremely successful in linking huge numbers of computers and users. However, to date, this technology has been oriented to computer interconnection in relatively stable operational environments, and thus cannot adequately support many of the emerging civilian and military uses that require a more adaptive and more easily deployed technology. In particular, multihop packet radio networks are ideal for establishing "instant communication infrastructures" in disaster areas resulting from flood, earthquake, hurricane, or fires, supporting U.S. military doctrine for reliable, secure infrastructures for communication among all tiers down to the soldiers "on-the-move," and extending the global communication infrastructure to the wireless, mobile environment. The Defense Advanced Research Projects Agency (DARPA) is sponsoring the development of wireless internet gateways (WINGs) as part of the DARPA Global Mobile (GloMo) Information Systems program.

this report describes key results in each of these areas. Selected papers describing more details on each of these areas, and listed in each section, are included at the end of this report. WINGS ARCHITECTURE AND PROTOTYPES 2.1 WING Architecture The DARPA packet radio and SURAN programs demonstrated the basic capabilities of ad-hoc networking. However, the ad-hoc networks proposed and implemented in such programs had been designed as opaque subnetworks using an intranet protocol for packet forwarding that enables packets to flow from one packet radio to the other and from one entry point of the ad-hoc network to an exit point. When the ad-hoc network is used as a subnet in an IP internet, one or more of the packet radios connect to the rest of the IP internet through IP routers in order to provide end-to-end connectivity. IP packets are encapsulated in intranet-level packets, and the routing functions within the ad-hoc network are carried out below the IP routing layer
