Energy-efficient cluster manager-based cluster head selection technique for communication networks

摘要

The Mobile Adhoc Network (MANET) is a distributed network without any standard infrastructure. In MANETs, several nodes in the network are grouped by which they can communicate with each other. Clustering is a grouping of mobiles nodes performs the communication process by means of optimal usage of available bandwidth and high network throughput. Several clustering schemes exist, but they suffer from the consumption of energy because of the cluster head's workload and increase in the number of clusters. In this paper, we propose a cluster manager-based cluster head selection (CMBCH) scheme to overcome the energy problems and leverage CH workload. CMBCH consists of two components, such as cluster manager (CM) and cluster head (CH). The CM takes the responsibility of controlling and monitoring of nodes activities. The CH leads and performing packet transfer among the nodes in the network. At this stage, when current CH energy level is drained, CM elects the corresponding node with high energy level and the new, as well as old CH activities, are simultaneously stored by CM. To prove the proposed scheme efficiency, a simulation experiment was conducted for 20 to 100 nodes under the AODV routing protocol. The network parameters packet delivery ratio and energy consumption are compared for the CMBCH,DLC and HCAL. The obtained results are compared to others; CMBCH conserves minimal energy and bandwidth and also achieves reliable throughput through stable routing.
