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...
This work discusses the adaptation of group-oriented messaging and chat technology for operation in serverless, multicast-capable mobile wireless architectures. The main goals are to allow group messaging and chat sessions to fragment/coalesce, operate through disrupted TCP conditions, and improve bandwidth utilization when multicast is available. In addition, the solution demonstrates proxying and...
