Abstract

This paper presents a performance analysis of the temporally ordered routing algorithm (TORA) protocol on top of IEEE 802.11a. IEEE 802.11a offers up to eight different coding schemes. Depending on the coding schemes the ad hoc routing behaviour differs. This paper describes the influence of the coding schemes, reviews the TORA protocol including the link reversal algorithm and presents the combined results. This research focuses on the application of TORA in a scenario where an ad hoc network is connected to the Internet using an ad hoc gateway. Special emphasis was spent to a separated investigation of the protocol performance for uplink and downlink routes. The paper presents three enhancements to TORA avoiding and finding loops. Simulation results are presented showing the performance of TORA on top of IEEE 802.11a and describing the feasibility of TORA to be used as routing protocol in ad hoc integration scenarios.
