A multiple constrained Qos routing algorithm based on hopfield neural network

This paper presents a multiple constrained QoS routing algorithm based on Hopfield NN. Multiple constrains conclude delay, bandwidth, delay-jitter, cost and so on. The expressions of network cost and path are given which is related with QoS and this problem can be regarded as a shortest path. Representing the shortest path problem as a Hopfield NN and establishing a NN model. Finally, an energy function is constructed which takes into account all objectives and constraints.
