Cellular IP network deals with micro mobility of the mobile devices. An important challenge in wireless communication, especially in cellular IP based network, is to provide good Quality of Service (QoS) to the users in general and to the real-time users (users involved in the exchange of real-time packets) in particular. Reserving bandwidth for real time traffic to minimize the connection drop (an important parameter) is an activity often used in Cellular IP network. Particle Swarm Optimization (PSO) algorithm simulates the social behavior of a swarm or flock to optimize some characteristic parameter. PSO is effectively used to solve many hard optimization problems. The work, in this paper, proposes an on demand bandwidth reservation scheme to improve Connection Dropping Probability (CDP) in cellular IP network by employing PSO. The swarm, in the model, consists of the available bandwidth in the seven cells of the cellular IP network. The anytime bandwidth demand for real-time users is satisfied by the available bandwidth of the swarm. The algorithm, used in the model, searches for the availability of the bandwidth and reserves it in the central cell of the swarm. Eventually, it will allocate it on demand to the cell that requires it. Simulation experiments reveal the efficacy of the model.

Real-time traffic in Cellular IP network is considered to be important and therefore given priority over non-real-time. Buffer is an important but scarce resource and to optimize Quality of Service by managing buffers of the network is an important and complex problem. Evolutionary Algorithms are quite useful in solving such complex optimization problems, and in this regard, a two-tier model for buffer, Gateway and Base Station, management in Cellular IP network has been propsed. The first tier applies a prioritization algorithm for prioritizing real-time packets in the buffer of the gateway with a specified threshold. Packets which couldn’t be served, after the threshold, is given to the nearest cells of the network to be dealt with in the second tier, while Evolutionary Algorithm (EA) based procedures are applied in order to optimally store these packets in the buffer of the base stations. Experiments have been conducted to observe the performance of the proposed models and a comparative study of the models, GA based and PSO based, has been carried out to depict the advantage and disadvantage of the proposed models.

In recent years many technologies have converged to integrated solutions and one of the hottest topics has been the deployment of wireless personal area networks (WPANs). In this article we present a generic architecture scheme that allows voice and other real-time traffic to be carried over longer distances. The proposed scheme is a novel framework that combines a wired backbone network including Bluetooth access points (APs) with the mobile Bluetooth-enabled devices of the end users. This scheme is called Bluetooth Promoted Multimedia on Demand (BlueProMoD). BlueProMoD is a hybrid network and provides free-of-charge communication among customers, multimedia advertisements, as well as location-based and other value-added services.

In this paper an IP based network consisting of two separate IP networks - a virtual one, running MPLS and an experimental IP network, connected to the virtual one, have been studied. VoIP traffic is exchanged between the two networks. Both networks are connected to the Internet and exchange traffic with it. The virtual network is created by using GNS3. The purpose of this paper is to show a comparison in the performance between the two IP networks. In addition, mathematical distributions and approximations have been made to be used to further evaluate the performance of the two networks. The used methodology in the present work can be applied in the study of different IP networks through which different types of real-time traffic passes.
