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 many
problems such as early detection of diseases, drug delivery,
pollution, extinction of organisms. The Internet of
macro/nano things is an infrastructure-less network and
communication range limitation is one of its challenges.
Intermediate nano-nodes could be used to overcome this
problem. However, intermediate nano-nodes may act selfish
and refuse to cooperate due to limited resources. To
overcome this problem, we propose a bio-inspired
distributed model using a trust and a voronoi-based
cooperation strategy with teams of neighbors. Using both cell
membrane inspiration for making a flexible joining and
parting and two metrics of trust and distance, we make a
mechanism to promote cooperation in the Internet of
macro/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 on
the 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.
