Presenting a new routing protocol to improve energy consumption and congestion control in MANET communication networks using fuzzy logic

With the advancement of wireless communication technology, MANET networks have attracted a lot of attention due to the improvement of flexibility and cost reduction. Mobile stations in a MANET are constantly moving, so a routing protocol needs to be implemented to cope with these changes. Designing such protocols usually brings special challenges and problems. One of these challenges is the possibility of congestion due to the high rate of sending information to the destination node and also the high energy consumption of the nodes. Congestion causes loss of information and waste of energy in nodes. Accordingly, in this article, in order to control congestion, a new method based on fuzzy logic is proposed. In the proposed protocol, fuzzy logic detects, announces and controls congestion by using three parameters of queue buffer length, node mobility speed and available bandwidth as inputs. By simulating the proposed method and comparing it with the CBP protocol, it can be seen that the proposed protocol has a much better performance than CBP for congestion control.
