an efficient cluster head selection algorithm in wireless sensor networks is proposed in this paper. the implementation of the proposed algorithm can improve energy which allows the structured representation of a network topology. according to the residual energy, number of the neighbors, and the centrality of each node, the algorithm uses fuzzy inference systems to select cluster head. the alg...

Over the last years, a number of query-based routing protocols have been proposed for Wireless Sensor Networks (WSNs). In this context, routing protocols can be classified into two categories, energy savers and energy balancers. In a nutshell, energy saving protocols aim at decreasing the overall energy consumed by a WSN, whereas energy balancing protocols attempt to efficiently distribute the ...

Tiny sensor nodes with limited energy sources and connected wirelessly are widely used for real time applications. Long distance data transmission towards base station with number of hops reduces overall wireless sensor energy consumption in the network. Here it is propose a dynamic routing protocol with hopping for better energy management as well as reducing delay in packet data transmission....

Wireless Sensor Networks have formed new opportunities across the variety of human efforts including engineering design, forest fire tracking, and battlefield surveillance. It is a group of sensor nodes that comprised of sensing, computing, and communication elements that gives an administrator the ability to observe and react to events and phenomena in a specified environment. Minimizing Energ...

In recent years, many approaches and techniques have been explored for the optimization of energy usage in wireless sensor networks. Routing is one of these areas in which attempts for efficient utilization of energy have been made. These attempts use fixed (crisp) metrics for making energy-aware routing decisions. In this paper, we present a generalized fuzzy logic based approach for energy-aw...

Due to non uniform distribution of nodes, there is an imbalance of energy consumption among the nodes in cluster-based wireless sensor networks. Based on this problem, we propose an efficient data aggregation tree for communication and routing based on the previous clustering architecture. Here based on the parameters such as Residual Energy, Node Density and Load cluster heads are elected usin...

Wireless Sensor Networks (WSNs) have inherent and unique characteristics rather than traditional networks. They have many different constraints, such as computational power, storage capacity, energy supply and etc; of course the most important issue is their energy constraint. Energy aware routing protocol is very important in WSN, but routing protocol which only considers energy has not effici...
