Abstract The main challenge of wireless sensor networks (WSNs) is to conserve energy of sensor nodes and to increase network’s lifetime. The energy efficient protocol is one of the most focused research issues in WSNs. Network layer routing protocols are proven to be more energy efficient when it uses clustering schemes. In this paper, with an objective to prolong the network’s lifetime we have proposed a timer-based, distributed, energy efficient clustering scheme for wireless sensor network and we have also presented the implementation details and comparison of the TEECS protocol with existing LEACH protocol. In the results, we found out that, the TEECS protocol was more energy efficient than the LEACH protocol.

1 Introduction WSNs comprises of self-organizing multiple nodes which are used for monitoring environmental and physical conditions like sound, fire, pressure, temperature, humidity, etc. The basic constituents of a node are sensing, data processing, N.

communication, and power unit. In most application, the sensor nodes are coupled with irreplaceable and limited energy source. Since energy plays a vital role in WSN, we must consider the energy efficient routing protocol to preserve the consumption of energy of each node and hence prolong the network’s lifetime. Clustering scheme is most effective means to save energy consumption and for managing enormous sensor nodes in WSN [1]. It minimizes the amount of nodes participating in the transmission of data to the Base Station (BS) [2]. The sensor nodes are grouped into distinct clusters using clustering process. One coordinator node is selected from the individual cluster known as a cluster head (CH). The non-CH sensor nodes inside each cluster act as cluster members (CMs). The CM senses its environment to collect data and send it to their corresponding CH. In this entire process, CH acts as a router. CH aggregates the received data and forwards this data to the BS using single hop communication. In most CH selection techniques, CHs are selected randomly. In such a technique, if the communication range to the BS is more and if the selected CH has a lesser amount of energy, then CH drains its energy more quickly. Also, if the CHs are not selected proper
