Wireless sensor network (WSN) is a system composed of a large number of low-cost micro-sensors. This
network is used to collect and send various kinds of messages to a base station (BS). WSN consists of low-cost nodes with
limited battery power, and the battery replacement is not easy with thousands of physically embedded nodes, which
means energy efficient routing protocol should be employed to offer a long network life time. The lifetime of Wireless
Sensor Networks (WSN) is crucial, so we need not only to minimize total energy consumption but also to balance WSN
load. Researchers have proposed many protocols such as LEACH, HEED, PEGASIS, TBC, PEDAP and GSTEB. In this
paper, we propose an improved General Self-Organized Tree-Based Energy-Balance routing protocol which builds
number of clusters in network and in each cluster GSTEB implemented and encryption is used for security purpose.
Simulation results show that improved GSTEB has a better performance than GSTEB thus prolonging the lifetime of
WSN.
