Network monitoring is today not only a process to merely gather information about the network status but also the basic step of further important activities of resource management and optimisation. Many network management processes start from the knowledge of the most up to date load status, and the measurement precision is of uttermost importance for an effective reaction. This paper presents a monitoring...
The performance demands imposed on sensor networks carrying heterogeneous connections are challenging and can be satisfied via the deployment of highly dynamic statistical multiplexing protocols which honor the traffic Quality Of Service (QOS), while utilizing the network resources efficiently. While the successful design of high-performance traffic multiplexing protocols requires accurate modeling...
Sensor association rules, which are a kind of behavioral pattern that aims to capture the temporal relations between sensor nodes, has proven to be a promising tool for improving wireless sensor network (WSN) performance and its quality of service (QoS) by participating in the resource management process and by compensating for the undesired effects of wireless communication. To prepare the data needed...
In this paper, we provide an online monitor and control approach to manage bandwidth allocations on a shared network infrastructure in a QoS-aware application setting. Accurate management of bandwidth allocations with a goal of maximizing the revenues is quite complex, due to the interactions among various data flows that dynamically share the network bandwidth. We adopt a heuristics-aided control...
802.11-based multi-hop wireless mesh networks have become increasingly prevalent over the last few years. Recently, a lot of focus has been on deploying monitoring frameworks for enterprise and municipal multi-hop wireless networks. A lot of work has also been done on developing measurement-based schemes for resource management and fault management in these networks. The above goals require an efficient...
IEEE P1900.4 is an emerging standard for optimized radio resource utilization where cognitive radio technologies are used for efficient spectrum utilization. In this paper, we design and implement a cognitive wireless network system based on open documents of IEEE P1900.4, and evaluate its performance using UDP streaming and HTTP download. Our experiments show interesting results that total network...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
In this paper, we introduce a pricing model that ensures efficient resource allocation that provides guaranteed quality of service while maximizing profit in multiservice networks. Specifically, a dynamic allocation policy is examined that relies on online measurements while each service class operates under a probabilistic bound delay constraint. We present a rigorous analysis of the properties of...
As Grid networks grows, the complexity of resource management in Grid networks dramatically increases. To manage the Grid resources efficiently, policy based resource management system is suitable. However, the policy which made at a moment could not be appropriate to other time because the condition of the grid resources with time space changes. Thus, in this paper, we propose asynchronous policy-based...
