In our previous work, we implemented the Linearly Decreasing Vmax Method (LDVM) for our WMN-PSO simulation system. In this paper, we implement a new replacement method for mesh routers called Rational Decrement of Vmax Method (RDVM). We use Size of Giant Component (SGC) and Number of Covered Mesh Clients (NCMC) as metrics for optimization. From the simulation results, we found that RDVM converges faster to best solution than LDVM.Peer ReviewedPostprint (author's final draft

    Implementation and evaluation of a simulation system based on particle swarm optimisation for node placement problem in wireless mesh networks

    With the fast development of wireless technologies, wireless mesh networks (WMNs) are becoming an important networking infrastructure due to their low cost and increased high speed wireless internet connectivity. This paper implements a simulation system based on particle swarm optimisation (PSO) in order to solve the problem of mesh router placement in WMNs. Four replacement methods of mesh routers are considered: constriction method (CM), random inertia weight method (RIWM), linearly decreasing Vmax method (LDVM) and linearly decreasing inertia weight method (LDIWM). Simulation results are provided, showing that the CM converges very fast, but has the worst performance among the methods. The considered performance metrics are the size of giant component (SGC) and the number of covered mesh clients (NCMC). The RIWM converges fast and the performance is good. The LDIWM is a combination of RIWM and LDVM. The LDVM converges after 170 number of phases but has a good performance.Peer ReviewedPostprint (author's final draft

    研究成果の概要 (和文) : 情報システムは、コンピュータ、センサ等の種々の情報機器を含んだ異種なものとなってきている。こうしたシステムでは、これまでの応答時間、スループット等の性能目標に加えて、新たにシステム全体の消費電力の低減が重要となってきている。本研究では、自律的な対等なプロセスから構成される完全分散型の大規模P2Pシステムを考える。ピア間の自律的な協調動作により、システム全体の消費電力を低減できる分散型システムの新しいモデル、特に消費電力については実際のコンピュータの消費電力の実測に基づいて、消費電力のモデルの構築を行った。このモデルに基づいて、ピア間の分散型の協調動作方式を研究し、評価を行った。研究成果の概要 (英文) : Information systems are composed of nodes like computers and sensors interconnected in networks. Here, we have to reduce the total electric energy consumed by nodes in addition to achieving traditional performance objectives. In this research, we proposed a power consumption model of a node to perform application processes. We first measure the total electric power of types of computers to perform application processes and then abstract essential parameters which dominate the power consumed by nodes. The power consumption model which we proposed is referred to as simple power consumption (SPC) model. Here, a computer consumes maximum poser [W] if at least one process is performed, otherwise consumes minimum power. Based on the SPC model, we proposed the energy-aware server selection (EA) algorithm and evaluated the EA model. In the evaluation, we showed not only the total power consumption of a server cluster but also the average execution time of each process are reduced
