An innovative paradigm for autonomic opportunistic communication

Objective

Haggle is a new networking architecture designed to enable communication in the presence of intermittent connectivity. By intermittent connectivity, we mean any type of network connectivity, including (but not limited to) Blue Tooth, 802.11, Ethernet whether it is local or through the Internet. We propose a radical departure from the existing TCP/IP protocol suite by exploiting application layer forwarding instead of network layer. We define a system that uses best-effort, context aware message forwarding between ubiquitous mobile devices to provide service when connectivity is local and intermittent. We use only functions that are absolutely necessary and common to all services.

The main components of Haggle are opportunistic forwarding, privacy, authentication, trust, and incentive to cooperate. We propose to completely specify this new communication model, implement it (including issues such as security, privacy, trustability, aging of information), evaluate it in a large scale experiment (500 to 800 nodes) and interact with sociologists to study its impact on Internet users.

We expect Haggle to enable a new family of applications with a high degree of spatial or logical locality. We refer to these areas of networking as communities, and provide explicit support for community formation and management within Haggle. We believe that this notion of community will make propagation of information in Haggle easier to achieve and control.
