Dynamics of random access game in Collaborative Ubiquitous Environments

Ubiquitous applications can gather environmental context and provide services without user intervention. In this paper, we stabilize the network into a steady state that sustains an appropriate contention window size (or equivalently, channel access probability) for each game node to achieve high efficiency and better fairness .We also take a game-theoretic perspective towards optimized resource allocation for network coding based Collaborative Ubiquitous Environments (CUEs). We focused on the definition of proper structures and mechanisms for collaborative ubiquitous environments which can provide agents with information, through their perceptions, and with means of action and interaction. Finally, we analyze the impact of these parameters on the probability of successful transmission and give some optimization issues. Numerical investigations show that our game theoretic techniques can yield an optimal operating point without intervention of external controller in CUEs.
