對以上兩種算法進行仿真,分別考察當用戶移動速度改變和入呼到達率改變時系統(tǒng)開銷及位置區(qū)大小的變化情況,并和傳統(tǒng)的算法進行比較,從而評價算法性能的優(yōu)缺點,分析其原因。 由于以上算法的推導是建立在理想小區(qū)形狀和簡化的運動模型之基礎上的,從而回避了實際小區(qū)形狀的不規(guī)則性、實際運動模型復雜性等問題,因此還有待于在具體的系統(tǒng)環(huán)境中對算法進行驗證。 五、參考文獻 [1] ,and ,Dynamic location area management and performance analysis,in IEEE .,1993,.
