Universal mobile telecommunication system (UMTS) networks should be deployed according to cost-effective strategies that optimize a cost objective and satisfy target quality-of-service (QoS) requirements. In this paper, we propose novel algorithms for joint uplink/downlink UMTS radio planning with the objective of minimizing total power consumption in the network. Specifically, we define two components...
In recent years, as the deployment of Wireless Local Area Networks (WLAN) in dense-urban areas is growing rapidly, it can be a perfect supplement for providing location information of users in indoor environments where other positioning techniques such as GPS, are not much effective. However, most systems only focus on the network deployment for positioning but overlook that the original purpose of...
In recent years, positioning systems for indoor areas using the existing wireless local area network infrastructure have become very popular and attractive. However, most systems only focus on the network deployment for positioning but overlook that the original purpose of these WLAN infrastructures is providing the required connectivity. Furthermore, experimental results related to such positioning...
Nowadays, Indoor Positioning Systems capitalize on the existing wireless local area network infrastructure and are very popular and attractive. However, most systems only focus on the network deployment for positioning but overlook that the original purpose of these WLAN infrastructures is providing the required connectivity. In this paper, we propose an innovative approach where WLAN planning and...
QoS-aware network planning becomes increasingly important for network operators and ISP alike as the number and heterogeneity of applications supported by networks continue to increase. We have proposed an architecture and methodology to support QoS-aware route planning for IPTV networks. The route planning problem was formulated as a residual bandwidth optimization problem and solved using GA-VNS...
Web services bonding with stateful resources are different from traditional web services. Because the state of those resources can be highly dynamic which make it difficult to discover and combine proper web services and fulfill clients' demand. This paper proposes a new method of web services description and registration based on WSRF (Web Service Resource Framework), aiming to provide real-time...
The rapid development of communication technology provides a enormous support for municipal mesh network. Nowadays many cities across the world have setup or prepare to setup wireless mesh networks (WMNs), includes Beijing city for its 2008 Olympic Games. However, Internet Gateway (IGW) placement, which is one of essential issues in a WMN design, has not been considered seriously in practice both...
A modern wireless network can be neither successfully deployed nor successfully expanded without proper planning. In this paper we consider the wireless mesh network (WMN) planning problem where not much work has been done. We propose a more realistic multi-objective approach to model this problem where the two conflicting objectives of total deployment cost and network throughput are to be optimized...
This work presents a planning methodology for multimedia networks based on a hybrid traffic model and an evolutionary optimization procedure. The methodology intends to optimize the sizing of network elements to comply with two QoS simultaneous network parameters as well as to promote network stability and cost efficiency. The hybrid traffic model deals with the multimedia network traffic as a combination...
DVB-H network planning and optimisation are essential tasks for the network operators in order to provide adequate service quality. As DVB-H can be deployed by using Single Frequency Network (SFN), the assumption for building maximum coverage within the SFN area is to use as powerful transmitters and as high antenna locations as possible. Nevertheless, in addition to the technical tuning, the complete...
