Performance of the Reliable All-informed Voice Networking (RAVEN) system in dynamic network topologies

The RAVEN system comprises several networking algorithms designed to provide improved quality of service (QoS) for multiple voice, video, and data sessions in a direct-sequence (DS) mobile packet-radio network. The focus in this paper is on the interaction between the adaptive-transmission protocol (ATP) and least-resistance routing (LRR), two of the algorithms the RAVEN system uses for efficient network throughput. The end-to-end (ETE) efficiency of the RAVEN system is dependent on the cooperation of these protocols, and we examine their performance under multiple mobility models. Each radio generates packet radio organization packets (PROPs) to update the routing tables. We examine the sensitivity of the network performance in terms of throughput and energy efficiency at the rate that PROPs are generated.
