| dc.description.abstract | 非協調式跳頻被認為是一項具抵抗阻塞能力的重要通訊技術。在非協調式調
頻系統中，節點可不事先交換金鑰的情況下在多個頻道上進行跳頻。當節點在相
同頻道上相遇時，他們就能夠與對方通訊。但是在已存在的系統中，他們都需要
事先分配節點一個角色(傳送端/接收端)。這些方法只能使用在收送對的通訊上面
(也就是當不保證每個收送對的的收者一定是扮演接收端的角色)。在本篇論文中，
我們提出三個對稱式跳頻演算法(也就是不需要事先分配每個節點一個角色)。我
們提出的方法可以保證節點在有限的時間內通訊且在非同步的環境下有高產
量。 | zh_TW |
| dc.description.abstract | Uncoordinated frequency hopping has been considered as an important
technique for anti-jamming communications. In uncoordinated frequency
hopping systems, nodes randomly switch over multiple frequencies without
pre-shared keys. Upon rendezvous on the same frequency, they can communicate
with each other. Existing schemes, however, require role (sender/
receiver) pre-assignment before frequency hopping. Such approaches only
support the communication between sender-receiver pairs (i.e., the communication
between a node pair whose receiver play a sender role is not guaranteed).
In this paper, we propose three symmetric frequency hopping algorithms
(i.e., no role pre-assignment requirement). Our proposed algorithms
have bounded maximal time to rendezvous and high throughputs under asynchronous
scenarios. | en_US |
