A Survey of Hybrid Cluster-based Energy- Efficient Routing Protocols in Wireless Sensor Network

Wireless Sensor Networks (WSNs) is one of the most rapidly evolving scientific domain, which is mainly due to the development of advanced small and low-cost sensor nodes with capability of sensing various types of physical and environmental conditions, data processing, and wireless communication. WSNs have many sensor nodes which have restricted battery power and these nodes have to transmit sensed data to the Base Station which dissipate high energy of these nodes. Therefore reliable routing of packets from sensor nodes to its base station is the most important task for these networks. There are many routing protocols developed for the efficient use of energy resources to improve the network lifetime. Along with some conventional Energy-Efficient routing protocol, some hybrid routing protocols are also proposed for different applications. In this paper, we give a survey of hybrid routing protocols for Wireless Sensor Network and compare their strengths and limitations.
