摘要: In this article, a generalized analytical model for the evaluation of different performance parameters IEEE 802.15.6 standard is proposed. The specifically designed purpose supporting body-sensors, e-health monitoring and human body communication. framework modelled using three dimensional Markov chain with backoff stage, counter retransmission counter, as stochastic parameters. To mechanism freezing, which occurs due to insufficient time period data packet transmission in allotted access dropped after certain recurrences incident, allocating next packet. Unlike previous models, dynamic or time-variant variable incorporated our proposed support mechanism. From model, we obtain expressions metrics such reliability probability successful delivery, throughput energy consumption. Using Monte-Carlo simulation results reliability, consumption varying offered load payload, are obtained Castalia simulator. compared an existing from present literature.
