The explosive growth of mobile video traffic brings a great pressure on LTE mobile networks. Deploying caches at the evolved packet core (EPC) and radio access network (RAN) in LTE mobile networks can efficiently relieve this pressure by reducing duplicate content transmissions. In this paper, we propose a collaborative caching framework for the LTE mobile network with caches deployed at the EPC and...
The explosive growth of online videos brings a great pressure on LTE mobile networks caused by huge mobile data traffics. Deploying caches at the evolved packet core (EPC) and radio access network (RAN) in LTE mobile networks can efficiently relieve this pressure by the way of reducing duplicate content transmissions. In this paper, we propose collaborative caching algorithms for the LTE mobile network...
With the rapid development of wireless networks and mobile terminals (MTs), cooperation among MTs in heterogeneous wireless networks is currently widely investigated. Cooperation among MTs has a lot of advantages such as increasing network throughput, decreasing file download time, saving energy. Traffic distribution, which means how to distribute the traffic to the cooperating MTs, is a key issue...
Peer selection is one of the key issues in wireless peer-to-peer (P2P) networks and most of the traditional methods and algorithms those have been proposed are only based on homogeneous network. However, networks in the future will be highly heterogeneous. Different kinds of wireless networks such as GSM, UMTS, WLAN, exist together in the same area and different networks have different features and...
Cooperation among mobile terminals (MTs) in heterogeneous wireless networks is currently widely investigated. Cooperation among MTs has a lot of advantages such as increasing network throughput, decreasing file download time, saving energy and so on. Since different cooperate MTs have different influence on quality of service and user's experience, MT selection becomes a key issue in MTs cooperation...
Peer selection is a multi-criteria decision making problem. In order to improve the accuracy of peer selection in mobile peer-to-peer (P2P) networks, this paper proposes an integrated approach of Analytic Hierarchy Process (AHP) and Grey Relation Analysis (GRA) to consider various correlative parameters in selecting the optimum peer. The proposed scheme comprises two parts. The first part employs...
