A Bio-Inspired Model For Emergence of Cooperation Among NanoThings

In the not too distant future, all the objects of various scales can be connected and build a new kind of Internet. This Internet-like structure can put an end to manyproblems such as early detection of diseases, drug delivery, pollution, extinction of organisms. The Internet of macro/nano things is an infrastructure-less network andcommunication range limitation is one of its challenges. Intermediate nano-nodes could be used to overcome thisproblem. However, intermediate nano-nodes may act selfish and refuse to cooperate due to limited resources. To overcome this problem, we propose a bio-inspireddistributed model using a trust and a voronoi-based cooperation strategy with teams of neighbors. Using both cell membrane inspiration for making a flexible joining andparting and two metrics of trust and distance, we make a mechanism to promote cooperation in the Internet ofmacro/nano things. In this architecture, a good reputation encourages each nano-node to cooperate and gain trust of others in a team of neighbors. A nano-node that is located onthe shortest path and has high level of trust will be selected to maintain cooperation. In contrast, a nano- node with a low level of trust parts from the team of neighbors and cannot send information. We compare the proposed work with the state-of-the-art incentive cooperation models like DECADE.Results show that the proposed model is completely distributed, adapts to fast changing conditions (dynamic joining/ parting) and achieves good cooperation value.
