The Internet has evolved from a service to transport simple text files into a platform for transporting a variety of complex multimedia services. The initial centralized management systems were not designed and are therefore not able to perform efficient management of Quality of Experience (QoE) for these complex services. Deploying an autonomic management system resolves these complexity issue...

We consider the problem of joint congestion control and resource allocation in spatial-TDMA wireless networks. The design problem is posed as a utility maximization problem subject to link rate constraints which involve both transmission scheduling and power allocation. Starting from the performance limitations of a centralized optimization based on global network information, we proceed system...

This paper deals with the problem of distributed resource allocation in multi-carrier MIMO networks, for energy efficiency maximization. The user-subcarrier assignment is jointly allocated together with the users’ transmit powers, subject to the constraint that each subcarrier can be used by only one user. To this end, a novel approach is proposed which merges the popular Dinkelbach’s algorithm...

Wireless ad hoc networks find great utility in situ ations where there is no wired base station infrastructure. For large networks wireless channel access needs to be performed in adistributed mann er. Orthogonal Frequency Division Multiple Access (OFDM A) is an emerging multiple access technique that is used in several new networking technologies. In this paper we study the use of OFDMA for ad...

We construct a simple model of monetary exchange where, as in Lagos and Wright (2003), trades take place in both centralized and decentralized markets. However, in constrast to Lagos and Wright, we allow for general preferences and introduce nonconvexities (indivisiblities) and sunspots. In the centralized market, agents can trade statecontingent commodities. We show that nonconvexities and sun...

In this paper, I review the evolution and characteristics of South Korea’s financial system since the early 1960s. The South Korean experiences are then used to argue that the distribution of the knowledge about valuable businesses varies with the stage of economic development. This has implications for the design of financial system. In the early development stage when low labor cost is the ma...

To attain the targeted data rates of next generation (5G) cellular networks requires dense deployment of small cells in addition to macro cells which provide wide coverage. Dynamic radio resource management (RRM) is crucial to the success of such heterogeneous networks due to much more pronounced traffic and interference variations in small cells. This work proposes a framework for spectrum man...

The main challenge in operating cognitive ad-hoc networks is the lack of a centralized controller performing resource allocation for different users in the network. In this chapter, a distributed power allocation scheme is considered for secondary users and its performance is analyzed when time average channel gains are substituted for instantaneous channel gains. In this way, it is not necessa...

The inter-cell interference (ICI) problem in OFDMA wireless systems is a major impediment to attain high rates particularly for cell-edge users in reuse-1 systems. Using centralized resource allocation to combat ICI is not practical, particularly in heterogeneous networks (HetNets), as they require intensive signalling about interference and channel state information that may not always be prac...
