Mobility and Address Freedom in AllNet

摘要

Mobile devices can be addressed through a variety of means.We propose that each device select its own addresses, wemotivate this choice, and we describe mechanisms for deliv-ering data using these addresses.Hierarchical point-of-attachment addresses are not effec-tive with mobile devices. The network has to maintain aglobal mapping between addresses and locations whether ornot the address is topological. Since this mapping is neededanyway, there is not much point in having the structure of theaddress encode device location. Instead, we have designeda network protocol, AllNet, to support self-selected address-ing. When data is transmitted over the Internet, a DistributedHash Table (DHT) provides a connection between sendersand and receivers.The advantages of self-selected addresses include the abil-ity of devices to join and form a network without any needfor prior agreement, and the ability to choose a personal,memorable address. When multiple devices choose the sameaddress another mechanism, such as signed and encryptedmessages, provides the necessary disambiguation.
