A Hybrid Optimized Protocol in WSN to Improve Network Lifetime

Abstract

Wireless Sensor Networks (WSNs) is an invented automation which is used in recent years to perform multiple tasks in various domains intelligently. In order to increase its efficiency various probabilistic models and approaches have been introduced in the preceding years. In WSNs, large numbers of Immobile Sensor nodes (SNs) which may be homogeneous or heterogeneous are deployed in a gigantic network area. These SNs have mainly three components i.e. processor, sensor and wireless communication device. SNs use its power throughout for collecting, combining, monitoring and transmitting data and they have restriction in terms of transmission power and battery life. Knowing this, many protocols have been developed based on probabilistic approach to overcome this issue. In this paper, we propose a new hybrid optimized protocol to reduce the energy consumption of SNs and increase the lifetime of WSNs. Then the proposed protocol is implemented and compared with the existing routing protocols in MATLAB and found that it outperforms better in terms of stability, network lifetime and gives better solution for energy efficiency as compared to other existing routing protocols in hierarchical heterogeneous WSNs.
