Title
Implementation and evaluation of autonomous collaborative discovery of neighboring networks
Abstract
Emerging mobile devices often want to discover neighboring networks in real time. For example, a mobile may want to know the capabilities of the surrounding WiFi networks so that it can intelligently determine which one to use next and avoid wasting scarce battery power to attempt to connect the wrong networks. Knowing the address of the authentication server in a neighboring network may allow a mobile device to authenticate with the neighboring network while the device is still using the current network to transport its user traffic, even before the device detects the radio signal from the neighboring network. The Internet Engineering Task Force (IETF) is developing a Candidate Access Router Discovery (CARD) protocol for a mobile device to discover the address and capabilities of access routers in a neighboring network. However, it requires all neighboring access routers to implement CARD and to dynamically exchange network information with each other and with the mobiles, which is difficult to implement especially when neighboring networks belong to different network providers. Furthermore, CARD can only allow a mobile to obtain the information a local network provider configures its CARD protocol to provide, making it difficult to provide consistent information from network to network and to support mobile devices that may need different information depending on their different networking capabilities and user applications. This paper proposes and evaluates a new approach for real time discovery of neighboring network information: Autonomous Collaborative Discovery (ACD). It is autonomous because regular mobile users and their devices act autonomously to collect information and make the information available to other mobile users and devices. It is collaborative as the autonomous actions of the mobile users and devices help each other to discover the information they want.
