ABSTRACT
Planning of energy-efficient protocols is critical for Wireless Sensor Networks (WSNs) because of the constraints on the sensor nodes' energy. The routing protocol should be able to provide uniform power dissipation during transmission to the sink node. In this paper, we present a self-optimization scheme for WSNs which is able to utilize and optimize the sensor nodes' resources, especially the batteries, to achieve balanced energy consumption across all sensor nodes. This method is based on the Ant Colony Optimization (ACO) metaheuristic which is adopted to enhance the paths with the best quality function. The assessment of this function depends on multi-criteria metrics such as the minimum residual battery power, hop count and average energy of both route and network. This method also distributes the traffic load of sensor nodes throughout the WSN leading to reduced energy usage, extended network life time and reduced packet loss. Simulation results show that our scheme performs much better than the Energy Efficient Ant-Based Routing (EEABR) in terms of energy consumption, balancing and efficiency.

f12-sensors-12-11307: Throughput for different WSNs with different sensor nodes.

Mentions: As can be seen in Figure 12 our SensorAnt performs much better than EEABR in terms of throughput; this is because our model prevents congestion when the traffic load becomes heavier by distributing it over multiple routes. This is done in our proposed method using a proactive mechanism during the period of data transmission from the sender to the sink which periodically checks the energy status of WSN and selects the path with a better function quality by assigning more pheromone to it through positive reinforcement while the paths with little energy will get negative reinforcement.
