The growing demand of mobile wireless internet access has prompted rapid growth of wireless data services. The key issue of wireless cloud is to provide complex services by using the available resources within reasonable cost. Accompanying the emergence of integrated wireless and mobile networks (e.g. WLAN, 3G/4G net), it makes a challenge of networks as service to supporting the complete lifecycle...
Mobile handset manufacturers are introducing new features that allow a user to configure the same handset for seamless operation with multiple wireless network providers. As the competitiveness in the wireless network service market intensifies, such products will deliver greater freedom for the mobile users to switch providers dynamically for a better price or quality of experience. For example,...
Relayed transmission is an interesting topic in cooperative diversity. Some researchers propose power allocation schemes for relayed transmission by only considering transmission through a fixed relay node. In our paper, we analyze a relayed transmission through a mobile relay node. We build up a transmission system model and determine the long term distribution characteristics of the movement of...
There is a problem of unfairness in allocation of radio resources among heterogeneous mobile terminals in heterogeneous wireless networks. Low-capability mobile terminals (such as single-mode terminals) suffer high call blocking probability whereas high-capability mobile terminals (such as quad-mode terminals) experience very low call blocking probability, in the same heterogeneous wireless network...
The Next generation wireless network (NGWN) will be heterogeneous in nature where different radio access technologies (RATs) operate together .The mobile terminals operating in this heterogeneous environment will have different quality of service requirements to be handled by the system. The radio resource management is one of the key challenge in NGWN. Call admission control is one of the radio resource...
The classical water filling problem is concerned with optimally assigning powers over n independent channels so as to maximize the total transmitted throughput. If each channel is associated with another mobile then it is natural to consider also the problem of fair assignment and to study tradeoffs between fairness and optimality. The object which is allocated is the transmission power, and we are...
Any single type of existing wireless and mobile network cannot provide all types of services, e.g., wide coverage and high bandwidth. An integrated wireless and mobile network is introduced by combining different types of networks to provide more comprehensive services. Although an integrated wireless and mobile network provides more connection options for mobile users than a single wireless and mobile...
