Energy efficiency analysis of a chain-based scheme via intra-grid for wireless sensor networks

This study proposes the ideal energy mathematical model for the ideal PEGASIS architecture. Since the distance between nodes is the same, this ideal energy mathematical model can obtain a longer network lifetime than that of the PEGASIS architecture in a WSN. To achieve this objective, the intra-grid PEGASIS architecture, which is architecture that is based on the PEGASIS architecture, is proposed. In the proposed architecture, the sensor area is divided into several network grids, and the nodes of each network grid are deployed at random locations, and the nodes in the network grid are connected. Finally, all of the network grids are connected. The results of a simulation reveal that the energy consumption in each round in the ideal PEGASIS architecture almost equals that in the intra-grid PEGASIS architecture, but the PEGASIS architecture consumes the most energy in each round. Additionally, only a tiny difference is found between the network lifetime of the ideal PEGASIS and that of the intra-grid PEGASIS architecture, and the PEGASIS architecture has the shortest network lifetime.
