A Stability-Aware Cooperative Routing Scheme in Multi-rate Mobile Ad-Hoc Wireless Networks

In this paper, we propose a stability-aware cooperative routing scheme in multi-rate mobile ad-hoc wireless networks to provide high data transmission with stable and reliable routes. The main features and contributions of the proposal are as follows: First, we use the cross-layer concept with network layer, MAC layer, and physical layer. Second, a stable routing path is selected as the main routing path. Third, we use the RSSI, PHY delay, and MAC delay for choosing relay and appropriate data rate adaptively. Forth, we derive mathematical models to investigate the tradeoff between point-to-point transmission rates and the corresponding effective transmission ranges. The performance evaluations through analysis and simulation demonstrate that the proposal can adaptively select optimal data rate and outperforms single rate routing protocol in terms of packet delivery ratio and network throughput in all settings of node density and node mobility.
