AMVS-NDN: Adaptive mobile video streaming and sharing in wireless named data networking

Recently, mobile traffic (especially video traffic) explosion becomes a serious concern for mobile network operators. While video streaming services become crucial for mobile users, their traffic may often exceed the bandwidth capacity of cellular networks. To address the video traffic problem, we consider a future Internet architecture: Named Data Networking (NDN). In this paper, we design and implement a framework of adaptive mobile video streaming and sharing in the NDN architecture (AMVS-NDN) considering that most of mobile stations have multiple wireless interfaces (e.g., 3G and WiFi). To demonstrate the benefit of NDN, AMVS-NDN has two key functionalities: (1) a mobile station (MS) seeks to use either 3G/4G or WiFi links opportunistically, and (2) MSs can share content directly by exploiting local WiFi connectivities. We implement AMVS-NDN over CCNx, and perform tests in a real testbed consisting of a WiMAX base station and Android phones. Testing with time-varying link conditions in mobile environments reveals that AMVS-NDN achieves the higher video quality and less cellular traffic than other solutions.
