由於無線的通訊及缺乏基礎的網路建設,在無線特定網路上的路由協定主要有兩項需克服的問題:分別是動態的拓樸和頻寬限制。目前無線特定網路上所提出來的解決方式可概分為表格驅動以及需求驅動兩種。表格驅動的協定法必須透過大量的控制訊息來維護即時的路徑資訊;需求驅動的協定法雖然減少了控制訊息的數量,但是在路徑取得的效率上卻不夠即時。因此要達到快速取得路徑的目的,又要減少控制訊息的數量以便節省網路頻寬,是一個無線特定網路上重要的研究議題。
本論文在無線特定網路上提出一個k-hop叢集式的距離向量路由方法,此路由法將擴展最小識別碼演算法來形成k-hop之叢集,叢集與叢集間則透過叢集管理者利用距離向量的方式來交換路由資訊,由於經過叢集管理者來管理整個網路的路徑資訊,除了可以減少路由資訊封包的交換數量外,在路徑取得的效率上也獲得相當的改善。此路由協定曾利用模擬與其他協定比較,證明在路徑取得與資料封包的傳輸上會有較佳之效果。
Due to lack of fixed infrastructure, routing in wireless communications by ad hoc network generates two research problems: dynamic topologies and bandwidth- constrained. According to how they react to the link state changes, the routing protocols for ad hoc network can be roughly categorized into 2 kinds, there are table-driven and on-demand. A table-driven protocol has to use a lot of control message to maintain the real time routing information, while an on-demand protocol use less control messages but suffer from inefficient route obtaining. How to achieve the goals of quick route obtaining and use less control packets is an important issue of ad hoc network.
In this paper we present a k-hop cluster-based distance vector routing to meet the requirements in wireless ad hoc networks. This routing scheme uses the lowest ld algorithm to construct the k-hop cluster, and the distance vector routing method which keep in the head node of a k-hop cluster is used to maintain the routing information of the networks. This routing scheme we present not only can reduced the number of routing information packets, but also improve the efficiency of route obtaining. By simulation, compared with other protocols and we found that our routing scheme is more efficient, and use less number of routing information packets.
