The Improved Efficiency Network Life-time in TEEN

Abstract In this paper, we’re compared network protocol which is network lifetime longer when using LEACH Protocol, SEP, and TEEN in a heterogeneous Wireless Sensor Network with a Large Sensor Area. Also, we propose a method of divided layer the wide-area sensor filed and transmitting a multi-hop to improve the network lifetime. And we’re compared network protocol which is network lifetime more improved apply the proposed method to LEACH Protocol, SEP, and TEEN. We tried to compare results, TEEN showed the best network lifetime. Apply the proposed method to divided the sensor field, L-TEEN (Layered TEEN)’s network lifetime rates of improvement is highest.

One of those utilizing wireless sensor network is a BSN. There are Homogeneous Network and Heterogeneous Network of the Wireless Sensor Network Type. Homogeneous Network is the same amount of energy of all nodes. Heterogeneous Network is nodes have different amounts of energy. According to the characteristics of the Wireless Sensor Network, it has been focused the study of the network lifetime. Various Protocols have been proposed to solve the problem of the network lifetime. It is to take advantage of the Wireless Sensor Network Protocol can improve the energy efficiency during the communication between the wireless device configured BSN. The typical protocol is LEACH Protocol, and continuously to improve and extend the LEACH Protocol. In addition, SEP and TEEN is proposed based on the concept of LEACH Protocol. LEACH Protocol is equally the energy consumption of sensor nodes selected by the Cluster Head random method. But LEACH Protocol does not guarantee to create ideal cluster. SEP is basically a Heterogeneous Network based Protocol and operations similar to LEACH Protocol, but the Normal Node and Advanced Node gives the threshold formula with a different Weighting factor. TEEN also operations similar to
