Routing-Gi: routing technique to enhance energy efficiency in WSNs

What is it about?

Wireless sensors networks (WSNs) are realized as one of the most promising networking types that bridge the gap between the cyber and the things. Designing of routing protocols for WSNs is a challenging issue since sensors are mostly limited in energy and data processing. In this paper, we present a new routing technique for hierarchical routing protocols to enhance energy efficiency in WSNs, namely Routing-Gi. This technique divides network area into the inner grid and clustered grids. In an inner grid, the nodes transmit directly data to the base station (BS), whereas, in the clustered grid, the nodes are organised into micro-grids and thus each node transmits data to the BS through it respective cluster head. in this case, the micro-grids help to avoid unbalanced energy consumption in WSNs. Thus, the workload is evenly distributed on nodes causing the efficient energy network to enhance. The simulation results prove the effectiveness of our technique.

Why is it important?

In this paper, a new routing technique, to enhance energy efficiency in WSNs, has been proposed, namely Routing-Gi technique. The main goal of Routing-Gi is to enhance energy efficiency in WSNs by decreasing the communication distance and the workload on CHs. To achieve this objective, our proposed technique divided the network area into grids. Each grid is divided into micro-grids, which minimizes communication distance between the nodes to CH, the closer nodes to BS, and CHs to BS. Thus, decreased communication distance and balanced energy consumption result energy efficiency in WSNs. The simulation results show that the routing protocols based on Routing-Gi are more efficient than existing protocols, such as LEACH, TEEN, SEP, and DEEC.
