Nowadays many applications use Wireless Sensor Networks (WSN) as their fulfill the purpose of collection of data from a particular phenomenon. Their data centric behavior as well as harsh restrictions on energy makes WSN different from many other networks known. During this work the energy management problem of WSN is studied, by using our proposed modified algorithm. It is a clustering algorit...

In this paper we are going to survey the application of particle swarm optimization (PSO) in WSN over different type of clustering based algorithm techniques like LEACH,LEACH-C, PEGASIS, etc In WSN sensors are randomly deployed in the sensor field which brings the coverage problem. Hence energy and coverage problem are very scarce resources for such sensor systems and has to be managed wisely i...

Energy efficient is the most important issue that must be solved in designing a qualified routing protocol for wireless sensor networks (WSNs) is how to save sensor node energy while meeting the needs of applications/users as the sensor nodes are battery limited. . There are number of various routing protocols have been proposed to optimize the efficiency of WSNs. From these protocols, cluster ...

The hierarchical routing protocol LEACH (Low Energy Adaptive Clustering Hierarchy) is referred to as the basic algorithm of distributed clustering protocols. LEACH allows clusters formation. Each cluster has a leader called Cluster Head (CH). The selection of CHs is made with a probabilistic calculation. It is supposed that each non-CH node join a cluster and becomes a cluster member. Neverthel...

When some nodes cooperatively track moving targets in a wireless sensor network, things including network working node selection and energy consumption are influenced. Thus, this paper proposes an improved algorithm LEACH-MTC (LEACH with Moving Target Constraint) based on low adaptive clustering hierarchy protocol (LEACH). First, the two-step linearization of nonlinear dynamic model, state targ...

In Wireless Sensor Networks life time of the network depends on the energy of the nodes, where energy consumption is mostly used for data transmission rather than sensing and processing. Also, in the WSN, the choice of routing protocol plays an important role in utilizing the energy of nodes efficiently. In this paper, a new novel routing protocol is proposed, which combines the two major categ...

This paper presents a novel approach to approve better network lifetime with the help of Swarm Intelligence (SI) technique which serves an ideal model of formulating routing protocols for WSNs. In this paper, wireless sensor network is firstly deployed and secondly the sensor nodes are communicated among themselves with the help of Ant Colony Optimization (ACO) so that it can find out the short...

Wireless Sensor Network (WSN) routing is complex due to its dynamic nature, computational overhead, limited battery life, non-conventional addressing scheme, self-organization, and sensor nodes limited transmission range. An energy efficient routing protocol is a major concern in WSN. LEACH is a hierarchical WSN routing protocol to increase network life. It performs self-organizing and re-clust...

Low-energy adaptive clustering hierarchy (LEACH) protocol is studied. A cluster head optimization strategy for wireless sensor network (WSN) is proposed by using univariate marginal distribution algorithm (UMDA). The novel routing protocol is named UMDA_LEACH. It considers the overall situation in the effect of all cluster head nodes with the help of probabilistic model. By so doing, it improve...

In Wireless Sensor Network (WSN), the life span depends on the energy consumption of the sensor node, by reducing the energy consumption of each node which in turn increases the lifetime of the network. Clustering is an effective technique to reduce the energy consumption. Low Energy Adaptive Clustering Hierarchy (LEACH) protocol is the first hierarchical cluster based routing protocol successf...
