Resumen |
In recent years, advances in miniaturization, low-power cir-
cuit design, simple, low power, yet reasonably efficient wire-
less communication equipment, and improved small-scale
energy supplies have combined with reduced manufacturing
costs to make a new technological vision possible, Wireless
Sensor Networks (WSN). As WSN are still a young research
field, much activity is still on-going to solve many open is-
sues. One is the data routing problem. As the size of the net-
work increases, this problem becomes more complex due the
amount of sensor nodes in the network. The meta-heuristic
Ant Colony Optimization (ACO) has been proposed to solve
this issue. ACO based routing algorithms can add a sig-
nificant contribution to assist in the maximisation of the
network lifetime and in the minimisation of the latency in
data transmissions, but this is only possible by means of an
adaptable and balanced algorithm that takes into account
the WSN main restrictions, for example, memory and power
supply. A comparison of two ACO based routing algorithms
for WSN is presented, taking into account current amounts
of energy consumption under a WSN scenario proposed in
this work. Furthermore, a new routing algorithm is defined |
