Abstract
One of the most critical issues in wireless ad hoc
networks is represented by the significant differences
in term of processing and energy power between the
different nodes, inducing a load imbalance between the
overloaded and idle nodes. Thus, making good
exploitation of the powerful nodes capacity by the
overloaded nodes if a fraction of their load will be
shared with other nodes is a must in ad hoc networks.
In this paper, we present a new load balancing
algorithm which is based on the grouping of nodes in a
set of clusters and to maintain a certain balance within
each cluster.
The objective of our work is double. On one hand it
aims at minimizing total tasks execution time and on
the other at extending the overloaded nodes lifetime
inducing a stability of the network.
The simulation results have shown that better network
performance can be reached by distributing load to idle
nodes of the network.
