WIRELESS communications and networking technology is the key to supporting a variety of applications such as the safety and emergency notification and infotainment applications a coalitional game framework for carry-and-forward-based cooperative packet delivery to mobile nodes in a hybrid wireless network. The mobile nodes are rational to form coalitions to maximize their individual payoffs. A continuous-time Markov chain model has been developed to obtain the packet delivery delay and the expected cost of mobile nodes for cooperative packet delivery. The packet delivery delay and the expected cost depend on the probability that each mobile node will help other mobile nodes in the same coalition. The users are mobile a coalitional game formulation to study how mobile nodes can dynamically form coalitions to cooperatively forward data of other mobile nodes in the same coalition. It is apply social network analysis to reduce the computational complexity of coalition formation. Two solution concepts, stable coalitional structure and core, are considered for the proposed coalitional game. A Nash bargaining game formulation to obtain Pareto-optimal solution for the probabilities that mobile nodes will help other mobiles in the same coalition. We perform a comprehensive performance evaluation of the proposed method. The proposed scheme consists of three interrelated steps. The SNA based mobile node grouping is done, the mobile nodes in each group play a coalitional game to obtain a stable coalitional structure.
