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...
We develop a space-centric routing protocol to enable the delivery of mobile VoIP over high-mobility multi-hop wireless networks. The novel aspect of this protocol is the attribution of network and MAC layer congestion to space, which provides delay guarantees over much longer durations than can be achieved by node-centric routing protocols. The presented protocol constructs a spatial map of network...
We propose a novel routing protocol, RMR, for wireless tactical, high-mobility military networks that finds reliable routes through difficult terrains with possibly compromised regions. RMR uses an end-to-end reliability measure that includes both end-to-end connectivity as well as trustworthiness, and reactively discovers routes over spatial cells whose local reliability is proactively maintained...
