Performance analysis of IEEE 802.11 ad hoc based broadcast

Abstract

Existing IEEE 802.11 broadcast performance researchers assume that the time taken for a successful frame transmission is the same as that taken for an unsuccessful frame transmission. They do not consider the effects of an extended interframe space (EIFS); therefore, their analysis and simulation results are not consistent with each other. This paper considers the effects of EIFS, modifies the model proposed by Hu, and uses throughput as a performance benchmark. Results of our study show that our proposed method yields results that are closest to the simulation results.

“…Therefore, the average probability that a node located within TA o can successfully receive node o's broadcast transmission, when N (SA o ) = k and N (PA o ) = n, can be calculated as: (9) where f (x|k) is the conditional probability density function of random variable X, which represents the distance from a randomly selected node to node o when N (SA o ) = k.…”

“…Besides, other details of broadcast transmission also attracted attention from researchers recently. For example, Huang and Kuo investigated the effect of the extended interframe space (EIFS) on broadcast throughput in [9].…”
