无线传感器网络中基于拍卖博弈的数据包转发算法

在无线传感器网络中，为了提高能量的利用率和增强数据包转发的可靠性，设计了PFAG（Packet Forwarding Algorithm Based on Auction Game）算法。该算法将数据包转发过程看作一种多阶段拍卖博弈过程，首先，网络中的节点根据拍卖博弈模型中的标价函数给出相应标价,然后基于双方博弈阶段最大化自己收益的原则，源节点可选出最佳的转发节点，从而找出最优的包转发策略。仿真结果表明，PFAG算法可有效的降低和平衡网络能耗，具备传输可靠性高和适应网络规模变化性强的特点。

Auction Game Based Packet Forwarding Algorithm in WSNs

In the wireless sensor networks, in order to improve the energy utilization and strengthen the reliability of packet forwarding, we designed the PFAG algorithm (Packet Forwarding Algorithm Based on Auction Game) in this paper. This algorithm treated the process of packet forwarding as a multistage auction game. Firstly, each node in the network give corresponding bid price on the basis of the bidding function, then basing on the principle of maximizing their own payoff in the game, the source node selects an optimal relay node so as to find out an optimal packet forwarding strategy. Simulation results indicated that the PFAG algorithm could effectively reduce and balance the energy consumption, promote the quality and reliability of transmission, while having preferable adaptability on the network size.
