SEMI AUTOMATED BARTERING OF DIGITAL GOODS AND SERVICES IN PERVASIVE ENVIRONMENTS

The vision of mobile personal devices querying peers in the environment for information such as local restaurant recommendations or directions to the closest gas station, or traffic and weather updates has long been a goal of the pervasive research community. However, considering the diversity and the personal nature of devices participating in pervasive environments it is not feasible to assume that these interactions and collaborations will take place with out strong motivating incentives. We propose development of a bartering communication model that incentivizes collaborations in pervasive environments by supporting peer to peer bartering for digital goods, services and information. To demonstrate feasibility of our approach, we propose to develop a middleware framework that will employ bartering protocols and strategies that will be context sensitive and allow taking advantage of personal relationships that exist between the owners of the devices that operate in pervasive environments. We propose to develop value based service descriptions to express the perceived valuation of information and services in a personalized manner. Our proposed bartering model will also rely on value based descriptions to efficiently control information and services that leave and enter each device. In particular, we plan to investigate the value in use and the value in exchange facets. To expand the space of possible deals during bartering, we propose to exploit social relationships between the owners of mobile personal devices that populate pervasive informants.
