Enhancing Lifetime of Wireless Sensor Nodes in Heterogeneous Environment

Abstract

The Wireless Sensor Network(WSN) consists of different sensor nodes. Each nodes having a specific amount of energy and deployed randomly in the network. The energy within the node helps in transmission of valuable packets among inter-connected nodes or directly to the Base Station(BS). While transmitting the packet, energy is not properly utilized. For proper utilization of energy, we used various parameters such as routing, probability, throughput and many more. In this paper, two approach is proposed for enhancing the lifetime of sensor nodes. In the first approach, we consider the normal nodes for becoming a part of cluster head(CH) selection. Here the energy and distance is considered as a key parameter. In the second approach, we consider the fitness parameter for enhancing the lifetime of the wireless sensor network. The protocol designed in this paper consider reduction in the various complex task for sensor nodes, enhance network lifetime and much more. Here five layer of network field is implemented which provides better performance. We have also done a comparative and detailed study of a specific protocol with two level of heterogeneity and CH parameter with the help of threshold value and many more.
