Masses of experiments have shown individual preference for fairness which seems irrational. The reason behind it remains a focus for research. The effect of spite (individuals are only concerned with their own relative standing) on the evolution of fairness has attracted increasing attention from experiments, but only has been implicitly studied in one evolutionary model. The model did not invo...

For designing broadcast protocols in mobile ad hoc networks (MANETs), one of the important goals is to reduce the rebroadcast packets redundancy while reaching all the nodes in network. In this paper, we propose a probabilistic broadcasting mechanism based on selfishness and additional coverage in MANETs. Our approach dynamically adjusts the rebroadcast probability according to the extra covere...

(This paper is not a paper; in other words, not even a draft. It is a compilation of different themes I have been thinking of during the last months. Being a compilation, the different "chapters" are not coherent. When I made changes in some chapters, these changes would have entailed that I change the content in other chapters too. But I have not had the time to do so. There are therefore all ...

According to the problem of the intermittent connectivity of the nodes in the delay-tolerant sensor network, considering that the nodes in the network are of social selfishness, we study how to reduce transmission delay and communication overhead on the basis of ensuring the message delivery success rate of the entire network. We present a delay-tolerant routing algorithm based on the node self...

To better understand how support for redistributive policies is shaped by macroeconomic shocks, we explore how distributional preferences changed during the recent “Great Recession.” We conducted identical modified dictator games during both the recession and the preceding economic boom. The experiments capture subjects’ selfishness (the weight on one’s own payoff) and equality-efficiency trade...
