Enhanced DHCP client

Published: 14 September 2007 Publication History

Abstract

The current network architecture for mobile devices presents applications with a synchronous model and employs end-to-end connections. In reality, devices are often disconnected from the network and, while they are disconnected, they can connect to other devices in the neighborhood and exploit the connectivity to allow the user to continue to work. This is the key concept of the Haggle project [1], a ground-up redesign of networking for mobile devices, to support the mobile user scenario. In order to benefit from users mobility, it is necessary to be able to opportunistically switch between (ad hoc) connections, whenever a new opportunity of connection arises. This imposes that connection set-up time must be minimal, considering that the nodes will probably stay in the range of each other for a short time frame. However, we saw that the 802.11 connectivity in Haggle carries significant overhead (especially when switching between Access Point (AP) mode and ad hoc mode, particularly when switching to AP mode) as the DHCP handshake takes a lot of time [2]. This suggested us to implement a new DHCP Client to speed-up the time for retrieving the IP during the connection to an AP, and to effectively implement opportunistic networking.
