Throughput Efficiency of Mobile Ad Hoc Networks with Node Classification Strategy

In this paper an analytical conclusion is present on the adjustment for the various transmission overheads, in order to upgrade bandwidth efficiency. The ad hoc network environment applications mostly have a lone sender, one or multiple end receivers and of course a number of intermediate nodes. The whole transmission scenarios can thus make it possible to classify nodes on the basis of various transmission states. The sender node has thus a prime impact on the performance of the whole transmission. Here we improve the sender performance dynamically which makes a ripple effect (improvement) on the overall transmission performance. Taking in consideration the aggregate throughput as the performance indicator across the nodes for bandwidth efficiency evaluation. It is taken into account the various overheads like minimum contention window etc. which lead to bandwidth deficiency in the ad hoc scenario. The results are being generated for the throughput across the nodes by reducing contention window, which help us to analyze the efficiency ratio of the various nodes for the current standard. The results are generated at various standard bandwidths and hence provide the insight about the distributed variation of throughput with respect to bandwidth. Our analysis is based on existing IEEE-802.11b standard. Finally we propose our conclusion by analytical description of the efficiency of the proposed solution at various standard bandwidths.
