Data Replication and Virtual Machine Migrations to Mitigate Network Overhead in Edge Computing Systems
(2017)Several virtual machine (VM) placement algorithms have been proposed and studied in the literature with various scopes such as server consolidation or network cost minimization. In most cases, decisions on VM migrations ... -
A double-auction mechanism for mobile data-offloading markets
(2015)The unprecedented growth of mobile data traffic challenges the performance and economic viability of today's cellular networks and calls for novel network architectures and communication solutions. Mobile data offloading ... -
Efficient file replication in large wireless networks with dynamic popularity
(2014)We investigate the problem of replication in large wireless networks that employ caching in the case of a single file whose popularity varies with time. As opposed to the case of static popularity, in this case for the ... -
Exploiting Caching and Multicast for 5G Wireless Networks
(2016)The landscape toward 5G wireless communication is currently unclear, and, despite the efforts of academia and industry in evolving traditional cellular networks, the enabling technology for 5G is still obscure. This paper ... -
Green video delivery in LTE-based heterogeneous cellular networks
(2015)In this paper we present an optimization framework that formalizes the inherent trade-off between the user perceived quality of wireless video, and the energy consumption cost of the network. The former is formulated in ... -
Load balancing in wireless sensor networks using kirchhoff's voltage law
(2009)We study load balancing in wireless networks with a single class of traffic, focusing our attention on an important example, i.e., Wireless Sensor Networks. The analysis is based on the Wireless Minimum Cost Problem, an ... -
Multirate multicast: Optimal algorithms and implementation
(2014)Multirate multicast improves user quality but complicates network optimization. This paper introduces a novel control scheme to dynamically optimize multirate multicast. We present MMT, an adaptive policy which combines ...
