A method for routing and data aggregating in cluster-based wireless sensor networks - 2021

Research Area:  Wireless Sensor Networks

Abstract:

Wireless sensor networks (WSNs) consist of a large number of small nodes, containing sensors; these sensors serve as powerful devices to gather data in different environments. One of the major challenges facing WSNs is their limited energy resources, which affects network lifetime directly. This paper provides a method of hierarchical routing and data aggregating for WSNs. In the proposed method, the network is clustered, and some nodes are selected as cluster heads. On constructing a rendezvous region and selecting backbone nodes, a tree is formed within backbone-tree nodes. The aggregated data are sent to the sink through backbone-tree nodes and cluster heads. Here, there are two modes of data transmission. The proposed method is simulated by Network Simulator (NS-2) software and compared with based data aggregation and rendezvous-based routing protocol. The results of simulation reveal that our method causes a decrease in end-to-end delay and energy consumption as well as an increase in the number of alive nodes and packet delivery rate.
