Abstract:
An enhanced performance analysis of a hierarchically structured access scheme for a Wireless Body Area Network (WBAN) is carried out in this paper. The access scheme uses the polling technique in each hierarchy level. Sensor nodes from first level are provided with infinite size buffers and both first and second levels use exhaustive polling technique. The study is done through computer simulation and mathematical models. Initially, the results of computer simulation are compared to the mathematical modeling. In spite of some approach used in mathematical modeling, the both results are very close. Next, to overcome the sensibility of second level to the input load of first level the performance analysis is carried out using different transmission rates for first and second levels.
