Enhanced DV-Hop Algorithm for Efficiency Energy and Network Quality in Wireless Sensor Networks

Abstract

Wireless Sensor Networks (WSN) are wireless networks with multiple sensor nodes covering a relatively large area. One of the weaknesses of WSNs is the relatively high energy consumption, which affects the network quality of service. Although WSN network routing using the DV-Hop algorithm is widely used because of its simplicity, improvements need to be made to improve energy efficiency, which impacts network lifetime. This article proposes a method to enhance energy efficiency by comparing the original DV-Hop algorithm with the enhanced DV-Hop algorithm. There are three approaches to enhancing the DV-Hop algorithm. Firstly, the CH node selection is based on the distance to the Base Station so that the selected CH node does not have a far distance from the base station. Secondly, the CH node selection must have a minimum number of sensor nodes as neighbors. Lastly, each selected CH node calculates the minimum distance to the previously selected CH node to ensure that the selected CH node is not in a nearby position. The proposed approach obtains better data packet transfer rate, energy efficiency, and network lifetime results using Matlab software simulation that compares the enhanced DV-Hop algorithm with the original DV-Hop algorithm and three other routing algorithms.
