In this paper, we study opportunistic traffic offloading in a vehicular environment, where the cellular traffic of vehicular users (VUs) is offloaded through carrier-WiFi networks deployed by the mobile network operator (MNO). By jointly considering users' satisfaction, the offloading performance, and the MNO's revenue, two WiFi offloading mechanisms are proposed: auction game-based offloading (<monospace>AGO</monospace>)...
The desire to increase bandwidth efficiency in an all-IP infrastructure in the presence of reduced spectrum and increasing demand for connectivity has led to several developments in IP header compression techniques. In recent years, there have been several IP header compression schemes developed in industry specifically for wireless networks including RObust Header Compression (ROHC) and IP Header...
It is of most concern by the operators who run multiple networks that how much traffic should each network carry to obtain the minimum cost for the operator. But it is left unanswered by current researches. A multi-dimensional traffic distributing algorithm for network cost optimization is proposed to obtain the optimal traffic distribution. In the proposed algorithm, multiple factors effecting traffic...
Compare with the voice service, mobile data service is more complex. It has many types of services according to different network resources and the customers' habits. It is found that mobile data business model plays an important role in helping operator understand the customers' habits, and market promotion. It can also be used in network optimization. The old ways to get the mobile data service...
