Energy-Efficient Load Balancing Ant Based Routing Algorithm For Wireless Sensor Networks, Xinlu Li, Brian Keegan, Fredrick Mtenzi, Thomas Weise, Ming Tan Aug 2019

Energy-Efficient Load Balancing Ant Based Routing Algorithm For Wireless Sensor Networks, Xinlu Li, Brian Keegan, Fredrick Mtenzi, Thomas Weise, Ming Tan

Institute for Educational Development, East Africa

Wireless Sensor Networks (WSNs) are a type of self-organizing networks with limited energy supply and communication ability. One of the most crucial issues in WSNs is to use an energy-efficient routing protocol to prolong the network lifetime. We therefore propose the novel Energy-Efficient Load Balancing Ant-based Routing Algorithm (EBAR) for WSNs. EBAR adopts a pseudo-random route discovery algorithm and an improved pheromone trail update scheme to balance the energy consumption of the sensor nodes. It uses an efficient heuristic update algorithm based on a greedy expected energy cost metric to optimize the route establishment. Finally, in order to reduce the …
