Router CPU Time Management using Particle Swarm Optimization in Cellular IP Networks

Providing QoS is one of the important issues in order to improve the performance of Cellular IP network. Resource reservation is often used in achieving this goal and it is proven to be an effective mechanism so far. Resources of Cellular IP network that can be reserved are bandwidth, buffer and CPU cycles. This paper is proposing a model for router CPU cycle reservation for real-time flows in Cellular IP network. The model applies Particle Swarm Optimization, as a soft computing tool, to reserve the CPU cycles and reduce the flow processing time at each router in the route taken by a flow. Simulation experiments reveal the efficacy of the model.
