Markov analysis of the mobile hidden station problem in MANET

This paper provides Markov analysis of mobile hidden station problem in the medium access control (MAC) layer of vehicular/mobile ad hoc networks (VANET/MANET). If a mobile station enters a collision free zone of any ongoing communication and interferes with this communication, it is called a mobile hidden station, and problems associated with mobile hidden stations is called mobile hidden station problem. The mobile hidden station problem severely degrades the throughput and the delay performances of mobile networks. In order to show the effect of mobile hidden station problem, the Markov models of IEEE 802.11 with and without mobile hidden station problem are developed. The developed models show that mobile hidden station increases collisions at the receivers and decreases the throughput up to 36 percent. This paper shows that mobile hidden station problem must be resolved while designing a MAC layer protocol for VANET/MANET.
