| dc.description.abstract | IEEE 802.16j 是一個剛訂完的都會行動無線多躍網路的協定。我們根據IEEE
802.16j 的特性，提出一種新的系統對位置管理的機制。這種機制結合了傳統的 地域性位置管機制和傳統的時間性位置管理機制。傳統地域性位置管理為將地 域化分成不同的區域，使用者每到一個新的區域時對新的區域提出註冊的動 作，系統了解使用這所在哪各區域內，系統並在訊息來時對此區域做出廣播的 動作。時間性位置管理為訊息來時，為定期更新使用都的位置，當訊息來時系 統跟據使用者最後一次的位置，使用者目前所有可能到的範圍做出廣播的動作。 為了確定這個機制的正確性，我們提供了一個新的命名法去命名IEEE 802.16j 下不同的基地台的所在的範圍。這個動的模型和隨機行走(random walk model)的模型一樣，但經由命名的方式，我們可以快速的得到使用都在哪一個基 地台下。除此之外，我們將這個機制的運做模式數學公式化，並最佳化得到結 果。比較數學的分析和模擬狀況下的結果來確定正確性；我們並討論在這個機 制下，給不同的訊息到達的頻率和不同的使用者移動的行動的特性。 | zh_TW |
| dc.description.abstract | According to the characteristic of idle mode of IEEE 802.16j, we provide a novel
location management scheme. It combines with paging area based scheme and timer- based scheme. The paging area based scheme is the paging and location update in di®erent areas. The timer-based scheme is that the system paging all cells users may be in and update location period. In order to guarantee the scheme's accuracy, we provide a rule to label the cells of IEEE 802.16j. The mobility model is also a random walk model and it can quickly get user's location at each cell. In addition, we formulate mathematical equations and get the optimized result. We compare the mathematical analysis result with the simulation result. We get characteristics about di®erent messages arrival rate and the variable mobility probability under our scheme. | en |
