摘　　要：鉴于传统合同网协议居高不下的通信量,本文提出了智能合同网协议(ICP).该协议对任务的发起者增加友好度因子,对投标者加入信任度因子,双方互相选择,并及时动态更新友好度及信任度;对每个动作添加时间因素,用全局时钟控制整个模型;为了降低通信量,防止投标者无限制投标,对投标者设定投标次数阈值;并且对于没有中标的任务则设定流拍的次数.根据历史投标记录,智能调整各项参数.本文利用颜色Petri网对ICP建模并仿真,实验数据证明,ICP极大的降低了通信量,缩短了运行时间,提高了任务命中率.In view of the high communication volume of traditional contract network protocols,this study proposes the Intelligent Contract network Protocol(ICP).The protocol adds a friendliness factor to the initiator of the task,a trust factor to the bidder,while two parties choose each other,and dynamically updates the friendliness and trust factors in time.It also adds a time factor to each task,and uses the global clock to control the entire model.In order to reduce the volume of communication,prevent bidders from bidding without restrictions,the protocol sets a threshold of the number of bids for bidders;and sets the number of unbid tasks.Based on historical bid records,various parameters are intelligently adjusted.This study uses colored Petri net to model and simulate ICP.The experimental data proves that ICP greatly reduces the communication volume,shortens the running time,and improves the task hit rate.
