提出了基于渗流理论的概率可靠分发协议(PLPD).与其他概率可靠分发协议不同,PLPD协议感知节点的地理信息并进行有向分发,不需要泛洪控制信息来进行组成员管理.在PLPD协议中,每个组成员只需维护其邻近区域中部分其他组成员视图,并以一定的概率向视图中的成员转发消息.采用渗流理论对PLPD协议的分发过程建模,从理论上证明了当分发概率参数大于某个阈值时,PLPD使每个消息被分发到所有组成员的概率为1.模拟实验表明,PLPD协议在获得高可靠性的同时有效地减少了网络负载,并在大规模移动自组网络中有较好的可扩展性.
(PLPD) based on percolation theory is proposed.Different from other probabilistic reliable distribution protocols, PLPD protocol senses the node’s geographical information and distributes it in a directional way without the need of flooding control information for group member management.In the PLPD protocol , Each group member only needs to maintain the views of some other members in the neighboring area and forwards the message to members in the view with a certain probability.Using percolation theory to model the PLPD protocol’s distribution process, When the probability of sending is greater than a certain threshold, the probability that PLPD distributes each message to all group members is 1. The simulation results show that PLPD can effectively reduce the network load while achieving high reliability, Self-organizing network has good scalability.
