Considering Backoff Algorithms Efficiency Focused on the Effect of Wall and Floor Materials for Indoor Radio Network

Abstract:

In this paper, we introduce a new theoretical scheme for evaluating the performance of backoff algorithms focusing on multiple types of wall and floor material such as: concrete, wood, glass and brick. The proposed scheme is an extension and combination between Bianchi and Multi-wall-floor model, by applying discrete Markov chain theorem. In addition, we also propose two backoff algorithms which can improve the saturated throughput efficiency of IEEE802.11 wireless local area network (WLAN). The proposed backoff algorithms are called Binary Exponential Increment Half Decrement backoff algorithm (BEIHD), and Half Binary Exponential Increment Double Decrement backoff algorithm (HBEIDD). The numerical results show that significant improvement saturated throughput of HBEIDD backoff algorithm operates well for plywood wall and wood floor materials in indoor environment.
