Incentive Driven Information Sharing in Delay Tolerant Mobile Networks
Mobile wireless devices (e.g., Smartphones, PDAs, and notebooks) play important roles in the people daily life, e.g., users often use such devices for bank transactions, keep in touch with friends. Users can also store such information and share with one another via opportunistic peer to peer links. However, peer to peer links are opportunistic links which are intermittent in nature and hence require the store-and-forward feature proposed in Delay Tolerant Networks to provide useful data sharing opportunities. Moreover, due to the limited resources, e.g., communication bandwidth and battery consumption, mobile devices can be selfish and may not be willing to forward data items to other devices that are interested in such items.
