Grid Based Cluster Head Selection Mechanism for Wireless Sensor Network
Abstract: Wireless sensor
network (WSN) consists of hundred to thousands sensor nodes to gathered the information
from physical environment. Different clustering based algorithms have been
proposed to improve network lifetime and energy efficiency. Practically it is
not feasible to recharge the battery of sensor nodes when they are sensing the
data. In such situation energy is crucial resource and it should be improved
for life span of WSN. Cluster head (CH) has an important role in hierarchical
energy efficient routing protocols because it receives data from nodes and
sends towards base station (BS) or sink node. This paper presents a grid based cluster head selection
(GBCHS) mechanism by dividing the network field into MXN uniform size
partitions that aims to minimize the energy dissipation of sensor nodes and enhancing
network lifetime. Simulation experiments have been performed in network
simulator (NS2) thatshow our proposed GBCHS approach outperformed than standard
clustering hierarchy LEACH protocol.
