Wireless sensor network are the networks which consists of hundreds to thousands of sensor nodes gathering various data including temperature, sound, location,etc. They have been applied to various fields such as healthcare, monitoring system, military, and so forth. Normally its very difficult to recharge or replace the sensor nodes which have limited battery capacity. Energy efficiency is thus a primary issue in maintaining the network. This paper proposes an efficient cluster head selection

It is based on the concept of finding the cluster head minimizing the sum of Euclidean distances between the head and member nodes. Computer simulation shows that the proposed system used approach allows better performance than the existing hierarchical routing protocols such as LEACH and HEED in terms of network lifetime.
