1、介紹了NDN的背景:(還需進一步的理解和補充。)
1)型型、節(jié)點
每個節(jié)點有三個數(shù)據(jù)集: the Content Store(CS), the Pending Table(PIT)鸿脓,the Forwarding Information Base(FIB).
cs:存儲數(shù)據(jù),存儲哪些數(shù)據(jù)由CS的存儲策略決定
PIT:stores the name prefixes that correspond to the INTEREST that the node could not satisfy and that it has sent to some other nodes; moreover, the node keeps track of the requesting nodes asking for the content?to send downstream the returned data
FIB:FIB registers the prefixes and the corresponding list of neighbors to forward INTEREST packets
2)妹懒、數(shù)據(jù)
發(fā)送的請求包含一個INTEREST 包雀监,其中包含數(shù)據(jù)名,selector and a Nonce; 響應(yīng)是DATA包眨唬;
3)会前、通信
節(jié)點向FIB列表中的鄰居節(jié)點發(fā)送INTEREST,當(dāng)任意一個鄰居節(jié)點收到請求匾竿,若cs含有請求數(shù)據(jù)瓦宜,則發(fā)送數(shù)據(jù)并丟棄INTEREST請求,否則岭妖,更新PIT临庇,將請求節(jié)點加入列表中反璃。如果FIB中的鄰居節(jié)點包含請求數(shù)據(jù),則將INTEREST 轉(zhuǎn)發(fā)給鄰居節(jié)點假夺。
2淮蜈、車輛移動軌跡選擇概率遵循Zipf分布:? ? ? ?http://www.cnblogs.com/peon/articles/6146230.html
在單詞頻率分布中,arfa在不同文本侄泽,值不同礁芦。P(r)為排名為r的單詞的出現(xiàn)頻率。
通過統(tǒng)計訪問排名和訪問頻率計算arfa和C悼尾。
3柿扣、formulate the optimal problem and use the simulation results to prove the influences of factors.
max 下載率(數(shù)據(jù)流行性+節(jié)點介入AS的概率決定)
在保證下載率不小于某一值后,min 緩存文件j的邊緣設(shè)備數(shù)
4闺魏、存儲設(shè)備的拓?fù)浣Y(jié)構(gòu)
5未状、指出數(shù)據(jù)流行行的穩(wěn)定性
6、數(shù)據(jù)下載過程
vehicle----->AP(若無則)---------->NDN node(還沒有則)---------------->producer
7析桥、NND司草,實在看不下去。pause
喜大普噴啊泡仗,數(shù)理統(tǒng)計過了B窈纭!
