在隨意型無線網路(mobile ad hoc network,MANET)中,無線網路的壽命依賴於行動端點的電池能量。在過去的研究中,有釵h架構在MANET網路的繞徑協定被提出,但是大部分的研究忽略了電池能量的限制因素。電池能量的缺乏將嚴重地衝擊在天然災害或不易建立通訊環境,如戰場所建立的通訊系統。本篇論文提出一個嶄新並具有能量知覺的繞徑協定,此方法可以增加電池能量的耐久性,進而延長行動端點與網路的壽命。此協定是藉由縮短行動端點的閒置週期並且不增加封包遺失的可能性或是減少繞徑的精確性。模擬的結果指出這個新的能量保存繞徑可以延長整個MANET的網路壽命。
The lifetime of a mobile ad hoc network (MANET) depends on the durability of the battery resource of the mobile hosts. Earlier research has proposed several routing protocols specifically on MANET, but most studies have not focused on the limitations of battery resource. The failure of battery resources severely impacts a communications system during natural disasters and in crucial communications environments, like a battlefield. This study proposes a new energy-aware routing protocol, which can increase the durability of the energy resource and, therefore, the lifetime of the mobile hosts and the MANET. The proposed protocol can conserve energy by shortening the idle period of the mobile hosts without increasing the probability of packet loss or reducing routing fidelity. Simulation results indicate that this new energy-conserving protocol can extend the lifetime of a MANET.
