Improving the Lifetime of Clustering-Based Wireless Sensor Networks by Considering the Conditional Dependencies in Inter-Cluster Routing
Considering the importance of energy consumption of cluster heads and the impact on the lifetime of cluster heads on the network lifetime, this paper addresses the issue of multi-hop inter-cluster routing. In the procedure proposed by the present study, first some analyses were done demonstrating that selecting the next hop for each cluster head is influenced by selecting the next hops for other cluster heads; therefore, to perform the inter-cluster routing, the dependency between the choices of next hops should be taken into consideration. Afterwards, we apply an evolutionary algorithm that is capable of taking these conditional dependencies into account in finding optimal routes between the cluster heads. In this evolutionary algorithm, the network lifetime is used as the fitness function for evaluating the solutions. The proposed method is evaluated using simulation and is compared to a classic routing method and two methods based on genetic algorithm (which lack the ability to take conditional dependencies into consideration). The results reveal that the proposed method improves the network lifetime.

Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information.
