On Demand Bandwidth Reservation for Real-Time Traffic in Cellular IP Network using Particle Swarm Optimization

Abstract

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.

Independent Tasks Scheduling using Parallel PSO in Multiprocessor Systems

“…However, unlike GA, PSO have no evolution operators such as crossover and mutation. In PSO, the potential solutions are called particles Anbar & Vidyarthi, 2011). In comparison to GA, the advantage of PSO is easy implementation.…”

“…Particle swarm optimization (PSO) is a meta-heuristic technique applied for an optimization problem that involves a large search space. This technique considers swarm of several particles as the potential solution of the problem (Anbar & Vidyarthi, 2011). Each particle is depicted by two parameters; position and velocity.…”

“…Resource reservation is one of the methods proven to be successful in improving QoS. Resource Reservation includes the most important resources in the network, such as bandwidth [1] and buffer [2]. Resource Reservation Protocol (RSVP) is a common protocol for resource reservation [3].…”
