| Ringkasan: | The deployment of Wireless Sensor Network(WSN) must
be done with some kind of advanced techniques so that it can
mitigate the energy constraints. An existing, clustered-based routing
protocol known as Low-Energy Adaptive Clustering Hierarchy
(LEACH) was studied, the outcome is an improved algorithm based
on LEACH. The performance of these algorithms was studied
through simulations using OMNeT++. In the original LEACH, the
Cluster Heads selections were based on a distributed algorithm. For
the modified algorithm, the improvement was done in the Cluster
Head selection process. The selection process takes into account the
residual energy of each node and used its probability outcome for the
determination of the threshold value for next round. The results
concluded that the performance of the modified algorithm is better
than the original LEACH, the outcome will result in maximizing
network lifetime. |
