Simulations show that using dual cluster head greatly decreases the message overhead for mute discovery and helps in extending the network lifetime 實(shí)驗(yàn)結(jié)果表明使用雙簇首極大地減少了路由發(fā)現(xiàn)過程中的信息開銷并且延長了網(wǎng)絡(luò)的生命周期。
Network nodes are divided into clusters in geocrp , sensor nodes send data to their cluster heads and these data are transferred between cluster heads until they reach the sink node , such a hierarchical network structure can increase scalability of the network Geocrp將網(wǎng)絡(luò)中的節(jié)點(diǎn)劃分成簇,感知節(jié)點(diǎn)采集的數(shù)據(jù)首先傳送到其所在簇的簇頭,再通過簇頭之間的通信進(jìn)行簇間中繼,直到到達(dá)匯聚節(jié)點(diǎn)。
A new algorithm is proposed that promises to deliver solutions to both the problems mentioned above , by using dual cluster head , which is very useful to minimize the use of epidemic algorithms of any sort , thereby saving a lot of resources and also making mute discovery more easier 本文提出一種能解決以上兩種問題的新算法,即在算法中使用雙簇首,可以減少任何形式的流行算法的使用,因而節(jié)約了許多資源并且使得路由發(fā)現(xiàn)更容易。
In the paper , the protocol adopt special route optimize algorithm and tdma time slot assigning algorithm , make node enter low consumption or sleep state in order to reduce the consumption ; aiming at choice the mechanism of cluster head , multi - hop routing and the mechanism of mac , the existing leach protocol is improved 本文的網(wǎng)絡(luò)協(xié)議是采用特殊的路由優(yōu)化算法和tdma時(shí)隙分配算法,使節(jié)點(diǎn)進(jìn)入低功耗或睡眠狀態(tài)以降低功耗。協(xié)議主要在簇頭的選擇機(jī)制、多跳路由、 mac層通信機(jī)制等方面,對(duì)已有的leach協(xié)議進(jìn)行了改進(jìn)。
