However, such studies often use abstract models for execution speed and simplicity. This article first shows that physical layer variables, including path loss, shadowing, multipath, and Doppler, have significant effects on the predicted overall networking performance. It then proposes an approach to simulate details of wireless propagation and radio characteristics in networking studies while still maintaining a reasonable simulation execution time. Through runtime performance studies with detailed orthogonal frequency division multiplexing (OFDM) Simulink\/MATLAB models and the QualNet network simulator, it is shown that the proposed approach can improve the simulation runtime performance by three to four orders of magnitude without compromising the fidelity of simulation results.<\/jats:p>","DOI":"10.1177\/0037549705049811","type":"journal-article","created":{"date-parts":[[2005,6,20]],"date-time":"2005-06-20T09:07:52Z","timestamp":1119258472000},"page":"241-253","source":"Crossref","is-referenced-by-count":5,"title":["Effects of Detailed OFDM Modeling in Network Simulation"],"prefix":"10.1177","volume":"81","author":[{"given":"Gavin","family":"Yeung","sequence":"first","affiliation":[{"name":"Computer Science Department, University of California, Los Angeles Los                         Angeles, CA 90095,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mineo","family":"Takai","sequence":"additional","affiliation":[{"name":"Computer Science Department, University of California, Los Angeles Los                         Angeles, CA 90095,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rajive","family":"Bagrodia","sequence":"additional","affiliation":[{"name":"Computer Science Department, University of California, Los Angeles Los                         Angeles, CA 90095,"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2005,4,1]]},"reference":[{"key":"atypb1","volume-title":"Proceedings of ACM\/SIGCOMM","author":"Misra, Vishal"},{"key":"atypb2","volume-title":"Proceedings of SPIE","author":"Yung, Tak-Kin"},{"key":"atypb3","first-page":"87","volume-title":"Proceedings of ACM MobiHoc","author":"Takai, Mineo"},{"key":"atypb4","first-page":"155","volume":"4","author":"Buck, J.
