A Multipath Routing Protocol Based on Clustering and Ant Colony Optimization for Wireless Sensor Networks

Free registration required

Executive Summary

For monitoring burst events in a kind of reactive Wireless Sensor Networks (WSNs), a Multipath Routing Protocol (MRP) based on dynamic clustering and Ant Colony Optimization (ACO) is proposed. Such an approach can maximize the network lifetime and reduce the energy consumption. An important attribute of WSNs is its limited power supply, and therefore in MRP, some metrics (such as energy consumption of communication among nodes, residual energy, path length) are considered as very important criteria while designing routing. Firstly, a Cluster Head (CH) is selected among nodes located in the event area according to some parameters, such as residual energy. Secondly, an improved ACO algorithm is applied in search for multiple paths between the CH and sink node.
