Investigation of Energy Efficient Routing Protocols in Wireless Sensor Networks on Variant Energy Models

Abstract

Practically, WSNs have multiple problems like communication, data processing, and sensor node management due to ambiguous and dynamic environments. In addition, WSNs have more challenging issues such as network routing protocols, sensor node assessment strategies, energy efficiency, and energy models. There is a need to develop new protocols that can provide efficient network management and extend the network lifetime. The concept of WSNs looks practical and exciting on paper, but the power consumption by an individual node is the main constraint of node performance. Various strategies that can be implemented to reduce the power consumption include (i) reduction in data transmission through data compression, (ii) lower the frequency and duty cycle of the data transmission, (iii) reduce the size of the frame overhead, (iv) efficient power management mechanisms, (v) scheduling an eventdriven transmission strategy, and (vi) develop energy efficient routing protocols. There are many authors that have considered the term energy efficiency from different viewpoints, but there are additional issues such as energy models, terrain conditions, mobility, scalability, and so on that still need more consideration to become more and more energy efficient. The foremost goal of this research is to evaluate and enhance the existing WSN frameworks.
