摘要: Recently, IEEE 802.15.6 standard has been established to optimize low-power in-body/on-body nodes serve a variety of medical and non-medical Wireless Body Area Networks (WBAN) applications. Coexistence entertainment sensors in the near vicinity is challenge terms Quality Services (QoS) guaranteeing interference mitigation. In order improve channel utilization by increasing number allowable transmission, enhancing overall performance, enabling integration different services, we propose combine Direct Sequence-Ultra Wide Band (DS-UWB) with slotted-Aloha random access. this paper, investigate performance proposed spread slotted Aloha for Standard processing gain scenarios models. Results indicate that relation between spreading code length combined sensor's contention probability strongest effect on system over
