摘要
Abstract
A statistics-based p-persistent CSMA algorithm is presented through the research on the CSMA algorithm . The bus competition is inevitable , and in that case the probability of data sent by the electric energy acquisition termi-nal on the bus is not invariable , whereas that is always computed in a statistical cycle .For this, the electric energy acquisition terminal regulates the p-persistent CSMA algorithm dynamically and prevents the bus competition to a cer-tain extent .Furthermore , it reduces the traffic volume of bus and optimizes the bus resources .In an aspect of preven-ting bus competition , this paper verifies the superiority of the statistics-based p-persistent CSMA algorithm by analy-zing the collision rate and comparing the performance among the non-persistent CSMA algorithm , the 1-persistent CS-MA algorithm and the statistics-based p-persistent CSMA algorithm .The data acquired in local database of electric en-ergy acquisition terminal shows that the statistics-based p-persistent CSMA algorithm can apparently improve the per-formance of collision rate in comparison with the other CSMA algorithms .关键词
