The Modeling of Cooperation of Nodes in Wireless Network Using Game Theory and Giving a New Solution To Stimulate The Nodes To Work With Each Other

In the conventional wireless networks such as mobile networks and sensor networks, the actions are oftencarried out based on the cooperation between the nodes. In such networks, every node plays the role ofhost nodes along with the role of network infrastructure. On the one hand it sends its data and on the otherhand leads the other packages of nodes. The network we aim to study is not a conventional one, it ratherhas logical nodes and theses nodes decide whether to cooperate freely or not. According to the fact thatthe leading of other packages has some costs for the nodes, the logical nodes tend not to lead to the datatraffic of the other ones. Therefore, we aim to model and analyze the cooperation of nodes using the gametheory. Then, we will present a strategy to stimulate the nodes to work with each other.
