【摘要】：針對無線傳感器網(wǎng)絡(luò)中如何利用有限能量延長網(wǎng)絡(luò)生存時(shí)間的問題,研究了分簇算法在能量異構(gòu)傳感器網(wǎng)絡(luò)環(huán)境下的性能特點(diǎn),設(shè)計(jì)出一種基于節(jié)點(diǎn)剩余能量,適用于多級能量異構(gòu)網(wǎng)絡(luò)的分簇算法。在該算法的網(wǎng)絡(luò)簇頭選舉加權(quán)概率中引入了參量γ,使得在簇頭選舉過程中,具有較高的初始能量和剩余能量的節(jié)點(diǎn)在簇頭選舉過程中當(dāng)選簇頭的機(jī)會增多。避免了剩余能量較小的節(jié)點(diǎn)擔(dān)任簇頭引起節(jié)點(diǎn)過早死亡使網(wǎng)絡(luò)覆蓋度降低的問題,從而均衡消耗網(wǎng)絡(luò)中的各節(jié)點(diǎn)能量,延長網(wǎng)絡(luò)的生存時(shí)間。同時(shí),引入簇頭管理機(jī)制保證了網(wǎng)絡(luò)每輪簇頭數(shù)目的穩(wěn)定,進(jìn)而提高了網(wǎng)絡(luò)的傳輸質(zhì)量。實(shí)驗(yàn)仿真結(jié)果表明,該算法在多級能量異構(gòu)網(wǎng)絡(luò)下比LEACH、SEP和DEEC具有較長的網(wǎng)絡(luò)生存時(shí)間和穩(wěn)定的數(shù)據(jù)傳輸能力。
[Abstract]:In order to solve the problem of how to use limited energy to prolong the lifetime of wireless sensor networks, the performance characteristics of clustering algorithm in energy heterogeneous sensor networks are studied, and a new method based on node residual energy is designed. A clustering algorithm for multistage energy heterogeneous networks. The parameter gamma is introduced into the weighted probability of cluster head election in this algorithm, so that the nodes with high initial energy and residual energy are more likely to be elected in the process of cluster head election. The problem of premature death of nodes with small residual energy as cluster head and the reduction of network coverage is avoided, thus consuming the energy of each node in the network and prolonging the survival time of the network. At the same time, the cluster head management mechanism is introduced to ensure the stability of the number of cluster heads per wheel, and then the transmission quality of the network is improved. The experimental results show that the algorithm has longer network lifetime and stable data transmission ability than LEACH,SEP and DEEC in multistage energy heterogeneous networks.
