AB  - Wireless Sensor Network (WSN) has been an object of extensive research activities around the globe
in recent decades. The WSN demands an efficient power management due to limited energy resources of the
nodes and it can be achieved by implementing the energy efficient protocols. Hierarchy based protocols are
recognized to be energy efficient. One of the most widely known hierarchical protocols is the Low-Energy
Adaptive Clustering Hierarchy (LEACH). However, the cluster head distribution in LEACH is only based on
the probability which is preset at the beginning of working procedure. Consequently, it can lead to the
unbalance in selecting the cluster head in regard of the position. Numerous research focus on wisely
distributing the cluster head position to achieve the prolonged lifetime of the network. In this study, we
propose a modification of the LEACH protocol. It is expected that the proposed protocol can extend the lifetime
of the system by incorporating the transmission distance between the network area and the data sink.
Simulation results show that the proposed algorithm demonstrates the improved performance over the
conventional protocol in terms of the network lifetime.
