本論文提出根據個人行為模式之行動IP技術(Personal Mobile IP, PMIP)用於改進行動IP(Mobile IP)的效能,不同於目前一般用來處理IP繞送和交握之固定網路架構的微行動協定(Micro mobility protocol)。個人行動模式之行動IP技術(PMIP)會依據個人不同的行為建構屬於個人行動區域(Personal Activity Domain, PAD)藉以提升行動IP效能。
在構成個人行動區域(PAD)的外部代理器中(Foreign agents),依據論文所提出的方法選出適當的區域管理路由器(Personal Activity Domain Root Router, PADRR),目的在於當行動通訊裝置(Mobile node)在個人行動區域中移動能夠正確傳輸資料並降低所產生的交握延遲(Handoff latency)。
個人行動區域建構完成時,行動通訊裝置在個人行動區域中漫遊並不需要每次移動至新的外部代理器都跟內部代理者(Home Agent)註冊,只有當快超過連結的有效時間(Binding Lifetime)時才必須重新註冊,因此可減少對內地代理者產生註冊訊號,藉以降低內地代理者的網路負載。
為了確保擁有較低的交握延遲和減少漫遊時對內地代理者所產生的訊號負載(Signal overload),個人行動模式之行動IP技術(PMIP)提供動態改變個人行動區域的方法,藉以維持較佳的行動通訊效能。提出之方法為利用偵測個人的行為模式是否有所改變,以決定更新個人行動區域與否。
最後並藉由實驗的分析來證明個人行動模式之行動IP技術的優點。
This thesis proposes a Personal Mobile IP (PMIP) protocol and mechanism to solve the IP mobility problem efficiently. Unlike the conventional mobile IP protocols that work in a fixed network topology for handling IP roaming and handoff, the PMIP approach constructs a Personal Activity Domain (PAD) for each mobile user, according to his/her personal roaming behavior. Among the Foreign agents (FAs) in the PAD, a Personal Activity Domain Root Router (PADRR) is selected for the associated user to take the responsibility of registering with the Home Agent (HA). The selection of PADRR is based on the goal of minimizing the signal message for HA, by an efficient algorithm developed in this thesis.
After the PAD is constructed, the registration from PADRR to HA asks for only when the lifetime of binding is expired. Then, the DRR takes care of all jobs for handling the roaming of associated user until the PAD is needed to be updated. In other words, it is not necessary for the mobile user to repeatedly register with the HA for hand-off, if he/she does not move across the boundary of his/her PAD. Therefore, the PMIP reduces the times of long-distanced HA registration from mobile user, by adopting short-distanced PADRR interaction, so that the hand-off latency can be reduced and the total performance of mobile IP system can be upgraded.
To guarantee low hand-off latency and roaming overhand, the PMIP applies a dynamic PAD strategy to always keep the most adequate PAD for each mobile user. An approach is developed to evaluate the dynamics of the roaming behavior of mobile user, and then determine if his/her PAD is needed for being updated to avoid the degradation of system performance due to the distinguished migration of user’s roaming behavior. In this condition, the user often moves across the boundary of PAD so that PMIP needs more time for hand-off than that of conventional protocols.
In this thesis, we develop the protocol of PMIP and associated algorithms. Besides, several analyses and experiments are made to confirm the advantages of PMIP.
