SCRRM: a stability‐aware cooperative routing scheme for reliable high‐speed data transmission in multi‐rate mobile ad hoc wireless networks

Abstract

SummaryIn this paper, we propose a Stability‐aware Cooperative Routing scheme for Reliable high‐speed data transmission in Multi‐rate mobile ad hoc wireless networks, called SCRRM, to provide high data transmission with stable and reliable routes. The main features and contributions of our proposed routing scheme are as follows: First, we use the cross‐layer concept with network layer, media access control (MAC) layer, and physical (PHY) layer. Second, a stable routing path based on link lifetime calculated from node mobility information is selected as the main routing path. Third, we use the received signal strength indicator (RSSI), PHY delay, and MAC delay for adaptively choosing relay and appropriate data rate. Fourth, we derive mathematical models to investigate the tradeoff between point‐to‐point transmission rates and the corresponding effective transmission ranges. The performance evaluation through analysis and simulation demonstrates that our proposed routing scheme can adaptively select optimal data rate and outperforms single‐rate routing protocol in terms of packet delivery ratio, network throughput, and average end‐to‐end delay in all settings of node density and node mobility.
