Multi-metric hop cost model is an efficient way to improve the performance of routing protocols. Depending on the network objectives and characteristics various parameters like hop count, energy consumption, relay load affect the overall hop and path cost. In this paper, we propose other metrics reflecting transmission channel effects to make paths costs more realistic. Analyses confirm the outperformance of the new hop cost model when compared with the other models.
