The main research in WSN is energy or power saving. Prolonging the network lifetime in WSN is research issue in field of sensor network. In cluster or hierarchical routing the cluster members send their sensed value to CH then CH relay the optimized and aggregated data to the base station. There are many ways to save the power of sensor nodes; one way is to reduce the unnecessary transmission of sensed data to the CH to BS. This paper focuses on using TEEN as an optimization algorithm for data transmission after cluster formation and then compares with DEEC variants and finally analyzes it in varying the nodes classification and initial energy of these groups of nodes. On comparing the proposed iP-DEEC protocol outperforms the traditional DEEC clustering protocols. Key Words: CH, SN, HWSN, WSNs, DEEC, EDEEC, DDEEC 1. INTRODUCTION Wireless sensor network represents the group of sensor network where the size of network can vary from a few to thousands [1-3]. Sensors relates the physical world to the virtual by sensing the surrounding environment then converting this information into a digital form then send it to the base station for the further processing [3,11]. Wireless sensor network consist of a large number of sensor nodes, which are connected wirelessly to collect the information from the sensing field. Clustering of sensor nodes can balance the load among sensor nodes which increase the network lifetime of sensor nodes in Wireless Sensor Network [8]. The modern technology development in the field of sensor design, material used and other ideas make the size smaller and compact of sensors and sensor arrays with lower cost [10,12]. Wireless sensor technology has potential for sensing and monitoring in not only science and engineering but also in a wide range of applications in military, structure health, industrial, child care, medical monitoring, food processing, surveillance and in many more fields [13,15]. 2. RELATED WORK DEEC [4] protocol is developed for heterogeneous network which have three types of different initial energy of nodes with weighted different probability for electing CHs. DDEEC [7] is the advance version of DEEC and this protocol resolve the penalizing effect of DEEC protocol. EDEEC [5], this is an extended version of DEEC with normal, advance and super node classification on the basis of nodeǯs energy. TDEEC [6] protocol is an improved version of DEEC and has three types of different energy nodes with modified probability function. EDDEEC [14] is the merged and improved version of E-DEEC and DDEEC protocol. Teen [9] protocol is a reactive protocol for time critical applications for data transmission optimization developed by A. Manjeshwar and D.P. Agarwal in 2001.This protocol decides the wanted set of value of sensed data to be transmitted from cluster head to the base station. Thus the desired value (like a range of temperature) should be greater than the hard threshold and the difference between the current sensed value and previously sensed value. Thus the network lifetime is extended. We used TEEN algorithm for regulating the data transmission after cluster head selection done by the EDDEEC. 3. MOTIVATION In many routing algorithm cluster head plays important role in choosing the best set of cluster head sets to ensuring the prolonged network lifetime. While there are many factors are considered by the researchers to develop the routing protocols for WSN such as average energy of the network, residual energy, probability of the being elected as CH, distance between the sensor nodes to the base station etc. Along with the sensing, data transmission in the wireless sensor network consumes the most of the power of the sensor nodes. The lesser transmission lowers the energy consumption, which results in prolonged lifetime of network. This research focuses on using TEEN concept for optimization of data transmission after the cluster formation in which the CH election is done according to EDDEEC protocol(Enhanced Developed DEEC purposed by N. Javed et al [14]) for three-level heterogeneous WSNs.
