無線感測網路的MAC通訊協定對於能源的消耗控制,扮演著很重要的角色,在有限制的能源前提下,如何有效地利用電力是很重要的議題,無線感測網路的MAC通訊協定最浪費電力的部分是在閒置 (idle) 等待的狀況,能夠讓裝置在閒置等待的這段時間適當的關閉無線網路訊號發射器是節省電力的重要關鍵,由於 PMAC 的作法可以讓長時間沒有傳輸動作的感測器快速的進入休眠狀態,這樣的做法可以大為改善感測器過聽 (over hearing) 的問題,也可以使整個網路架構充分地適應實際的傳輸流量而不會產生過多的能源消耗,但是這種設計需要精確的時間同步機制。在感測網路架構中,要達到時間的同步卻是非常消耗能源、非常昂貴的一種機制,當達到目的的同時也會產生多餘的能源消耗,減少感測器的生存時間。另外,每次週期後與鄰居感測器的樣板 (pattern) 交換動作,不僅產生了額外傳輸資料的能源消耗,同時也伴隨著傳輸過程中,競爭、碰撞與樣板交換失敗等等的因素。在我們這篇文章中,將提出一種非同步的網路運作架構 AMAC (Asynchronous MAC protocol) 期待在 PMAC 的機礎架構下,改善睡眠排程交換所造成的能源浪費與時間同步的問題。
The MAC protocol for wireless sensor network plays a very important role in the control of energy consumption. It is a very important issue to effectively utilize power under the condition of limited energy. The most energy-wasting part of the MAC protocol for wireless sensor network is at the idling condition, therefore it is crucial for power saving to be able to turn off the signal transducer of the wireless network when the equipment is idling. PMAC allows sensors that did not transfer for a long period of time to quickly enter a dormant state, so that the problem of sensor overhearing can be greatly improved, and the whole network structure can fully respond to the actual transfer rate without too much energy consumption, but this type of design requires precise time synchronization mechanism. To achieve time synchronization is a very energy-consuming and very expensive mechanism in the sensor network structure, achieving goal is coupled with excess energy consumption and reduce the lifespan of the sensor. Additionally, the exchange action with the neighboring pattern after each cycle, not only generates additional energy consumption for data transfer, but also accompanied by factors such as competition, collision and pattern exchange failure. We now offer an Asynchronous MAC protocol (AMAC) in this article and expect to improve the problem of energy wasting and time synchronization due to sleeping schedule exchange under the PMAC basic protocol.
