Dynamic Cluster Head Selection Mechanism For Wireless Sensor Networks

Abstract

For data transmission in wireless sensor networks (WSNs), routing is the main course. Many routing algorithm have been proposed for effective data transmission. For data transmission, dynamic cluster selection is necessary to create in the network. Dynamic cluster selection is performed based on energy level of node. Node with higher energy becomes cluster head, after cluster head node is selected; cluster head collects the data from every member of the cluster and forwards that to base station. Cluster head is rotated based on energy level. Proposed mechanism confirms data transmitted effectively and energy efficiency of the node increase. It is implemented using simulator NS2.34 along with TCL script.Keywords: Wireless Sensor Networks, Dynamic Cluster, Energy Efficiency, Routing Algorithm IntroductionIn wireless sensor and actor networks (WSANs) Decreasing of the energy may usually explore leading to dead node. So that succeed in dealing with this problem, there is an important matter at the point of separate single device and it attempts the data routed. This route contains following way that is at the time of contact between the nodes their energy expenditure is fewer amounts to hold their respective energy, rather than path of the routing data maximize their energy expenditure. One main thing it makes networks more faulttolerant is energy backup. Then these node having enough amount energy, itself only remove the failure, this is important thing. These sensor nodes characteristic of minimum cost, minimum power and universal functional have been generally used in the military services, industry, traffic, environmental security and etc. domains. Specifically in the shortage of the existence of the backbone network, including the dangerous region that man cannot make it happen, the battlefield, and other dangerous areas, the applications possible customer of wireless sensor systems surely will be great. Presently, the kinds of researchers have gained wealthy achievements. Security [16] [17] is fundamental things of the WSN and aim is to maintain freshness in data, it protects the local properties, cost usage is efficiently. Security will help when communication with false data. SPIN [15] is the data centric protocol of WSN. It is the different approach and its focuses on spread or delivery the data through network. In DC routing [3], one node collect the all other child node data then send to destination node. SPIN protocol using same procedure. This is the adaptive protocol. Dynamic cluster head selection mechanism guarantees the data delivery from source node to base station. Aim of the proposed scheme is to reduce the intercommunications distance between the nodes and also distances between the cluster head by means of route shorten method. For transferring the data, this scheme does not send the data packet throughout the network but clustering algorithms used for same. This proposed scheme, executed less number of packet transmission moreover these algorithms will consume less energy and sign...
