In last few years, there has been a growing interest in the area of Wireless Sensor Networks (WSNs). Now a day's WSNs are being deployed in large sensing areas for real life applications [1]. As sensor networks has limited and non-rechargeable energy resources, prolonging the lifetime of WSNs is a great issue. Some sensor nodes of comparatively high energy(More)
One of the fundamental problems in wireless sensor networks (WSNs) is localization that forms the basis for many location aware applications. Localization in WSNs is to determine the physical position of sensor node based on the known positions of several nodes. In this paper, a range free, enhanced weighted centroid localization method using edge weights(More)
In CMOS circuits, the reduction of the threshold voltage due to voltage scaling leads to increase in sub threshold leakage current and hence, static power dissipation. In the nanometer technology regime, power dissipation and Process parameter variations have emerged as major design considerations. These problems continue to grow with leakage(More)
Clustering in wireless sensor networks (WSNs) is an important technique to ease topology management and routing. Clustering provides an effective method for prolonging lifetime of a WSN. This paper proposes energy efficient multilevel clustering schemes for wireless sensor networks. Wireless sensor nodes are extremely energy constrained with a limited(More)
Clustering in wireless sensor networks (WSNs) is an important technique to prolong lifetime of a WSN. This paper proposes energy efficient multi-level clustering scheme called Power Aware Multi-level Clustering (PAMC) for homogeneous wireless sensor networks. Further, we also apply the proposed multi-level clustering scheme for heterogeneous wireless sensor(More)
Wireless sensor networks (WSNs) do not always have sensor nodes of same type. In other words, WSNs are not always homogeneous, but some sensor nodes of higher energy can be used to prolong the lifetime and reliability of WSNs. Heterogeneous wireless sensor networks (HWSNs) have some sensor nodes of relatively higher energy. HWSNs are very useful in real(More)
The impact of energy based heterogeneity is investigated through Source Initiated Reactive algorithmfor event driven applications to understandthe impact of heterogeneous network on energy ef?ciency and network lifetime. Based on the simulated experimental and numerical results, it is found that the energy ef?ciency performance is enhanced by 24% for(More)
In this paper we present a productive Load sharing routing technique to enhance the life time of the nodes in a manner to improve the overall life time of system. The existing routing techniques are used to choose a nominal effort to minimize the transmission time for Wireless Sensor Networks since they do not consider the energy utilized by nodes for(More)
