includes layer interface

The MAC protocol proposed in the thesis includes layer interface, link assignment strategies, slot structure and packet structure etc. Updating three information tables periodically achieve channel access and mapping. At last the results show that the average delay chi flat iron store decreased when using directional antenna instead of isotropic antenna arrays. Using the antenna new shoes 2010 array also affects the capacity gain and network throughput. Every node not only can access channel fairly without interfere using discount wedding prom dresses, but also increase the netowork connectivity.Network node model and directional antenna model are designed based on soft tool wedding dresses 2010 and the emulation of special network models is realized. According to the results, STDMA protocol ensures that connectivities per node achieve 4.8 and time of topology stabilization is less than 8 Epoches. Comparing with cheap evening dresses, up to 60% throught ugg boots 2010 improvement is achieved and delay controls within 250ms by utilizing SDTMA protocol with directional anntena. This protocol not only achieves requests of design, but also guarantees efficiency and stabilization.
