Since its development for WLAN, IEEE 802.11 standard has been widely used for various wireless networks due to the low cost and effectiveness in reducing collisions with simple and decentralized mechanisms. In this paper we present a novel analytical SRN model for performance evaluation of IEEE 802.11 DCF MAC protocol in multi-hop ad hoc networks in the presence of hidden nodes, taking into account the characteristics of the physical layer, different traffic loads, packet size, and carrier sense range. The proposed model captures most features of the protocol. Performance measures such as throughput and packet service time for various network configurations are computed. The proposed models are validated through extensive simulations.
