International Journal of Smart Sensor and Adhoc Network

Abstract

WSN consisting of a large number of small sensors with lowpower transceivers can be an effective tool for gathering data in a variety of environments. As sensor nodes are deployed in sensing field, they can help people to monitor and aggregate data. Researchers also try to find more efficient ways of utilizing limited energy of sensor node in order to give longer life time of WSNs. Network lifetime, scalability, and load balancing are important requirements for many data gathering sensor network applications. Therefore, many protocols are introduced for better performance. The lack of infrastructure and dynamic nature of mobile ad hoc networks demand new networking strategies to be implemented in order to provide efficient end-to-end communication. Some researches have been proposed to organize the network into groups called clusters and use different routing protocols for inter and intra clusters to propagate an information. But with these solutions, the network first needs to be organized into cluster and next, we need to construct each routing table[16]. In the available literature, multi-hop routing protocol is well known for power saving in data gathering [5]. Researchers have used such types of the cluster-based (e.g., LEACH, EERP), the chain-based (e.g. PEGASIS) and the tree-based (e.g. TREEPSI) to establish their energyefficient routing protocols. In this paper, we propose an improved version which uses both cluster and tree based protocols. The proposed protocol improves the power consumption by improving FND.
