ABSTRACT:
Wireless sensors networks consist of a number of sensors nodes
connected through a wireless network that collect data to be treated
locally or relayed to the sink node using multi-hop wireless transmission. Several
solutions were proposed to minimize the amount of information flowing within the
network. Clustering algorithms is one solution and mechanism that enables the
creation of sensor’s clusters; each sensor is dominated by elected routers. In
order to limit energy consumption, the clustering around the sensor is
established: sensors linked to the router transmit relayed data thereafter
outward. The number of messages sent and the transmission range are thus
reduced. This article tackles this issue by unveiling proposed techniques in
the same line of researches and proposing a clustering mechanism based on the
amount of energy remaining in the sensors. The simulation results show that
proposed method can achieve higher network lifetime by comparison to original
LEACH.
