应用于WBAN的动态自适应网络研究

Dynamic adaptive network researching applied in WBAN

基于WBAN的技术尚不成熟,提出一种新型WBAN技术方案,将HBC技术与MICS频段结合应用到WBAN中。考虑到体域网中体内节点的能耗约束性,提出了一种应用于WBAN的新型网络,即具有自适应性的基于中继的两跳星型网络;针对WBAN中节点生存周期的重要性,提出一种低能耗的MAC协议——基于TDMA的中继MAC协议。该方案的提出,能够满足WBAN对安全、能耗、可靠性等服务质量(QoS)的要求,且较好地改善了体内节点的网络生存期。

For the WBAN technology is still immature, a new technology solution of WBAN is proposed. Which is used in WBAN combining HBC technology and MISC band. Concerning about the energy binding of the intro-body nodes in body area network, the two-hops star network which has good adaptability based on relay is presented for the WBAN. For the importance of the nodes＇ lives cycle in WBAN, a lower energy consumption relay MAC protocol which based on TDMA is proposed. The scheme can satisfy the QoS requirements of WBAN such as the security, the energy consumption and the reliability, and well improve the network life- time of the intro-body node.
