Comparison between Flat and Hierarchical Routing Protocols in Wireless Sensor Network

Wireless Sensor Network (WSN) has delivered the accessibility of small, tiny and low cost sensor nodes which are capable to sense various kinds of physical and environmental conditions, data processing, wireless communication and data gathering. In wireless sensor network routing protocols can be divided into two categories first is flat routing protocol and another is hierarchical routing protocol. In this paper flat and hierarchical routing protocols are evaluated and compared based on various performance parameters. In the last decade we have seen expanded enthusiasm for the potential utilization of remote wireless sensor systems (WSNs) in an extensive change of uses and it has turned into a unique research zone. So finally, in this research paper we are focusing on two different classes of routing protocols in WSN: flat routing and hierarchical or clustering routing.

A Survey of Chain Cluster-Based Routing Protocols in Wireless Sensor Network

Over a period, Wireless sensor networks (WSNs) have turned out to be continuously increasingly appealing and discovered the way into a wide assortment of uses and also frameworks in view of their relatively inexpensive, self-sustaining ability, and their detecting capacity in harsh environment. It is a collection of hubs composed onto a system. Based on their routing architecture they are generally separated into two classes: Hierarchical routing topology and Flat routing topology. In a flat routing topology every nodes will have the similar use and they perform similar task presented by the network. Nodes present in hierarchical topology carry out unique tasks and they are normally formed into clusters in WSNs. In this paper, a detailed study is made on chain cluster-based routing schemes for WSNs and few comparisons made by considering performance features such as Fault tolerance, scalability and topology Strengths and limitations of each scheme and the same is presented.

Rethinking Cluster-based Routing in Wireless Sensor Networks

A wireless sensor network (WSN) can be employed in many application areas such as traffic control and industrial automation. In WSNs, clustering achieves energy efficiency and scalable performance. A cluster is formed by several sensors nodes, and one of them is elected as cluster-head (CH). A CH collects information from the cluster members and sends aggregated sensed data to the base station (BS) or another CH. The main task of a routing protocol in a WSN is to forward these sensed data to the BS. This paper analyses the advantages of cluster-based routing protocols vs. flat routing protocols in WSNs.
