We present an empirical model of the upstream end-to-end Voice-over-IP (VoIP) delay over a mobile, multi-hop wireless network towards a single gateway. First, we define the “VoIP regime” as the regime of network operation in which a fraction 1 - ϵ of the packets are received by the gateway within the maximum tolerable VoIP networking delay yvoip, and such that e is less than a maximum tolerable outage...
The integration cellular networks, wireless local area networks (WLANs), and the new paradigm of mobile ad hoc networks (MANETs) is the trend for next generation mobile networks. And the multi-hop routing mechanism is an open and challenge issue in this area. In this paper, a multi-hop routing mechanism with fuzzy estimation of links for heterogeneous wireless networks (HWNs) is proposed. The mechanism...
