An Uneven Cluster-Based Routing Protocol for WSNs Using an Integrated FCNP-VWA-ELECTRE

In WSNs, sensor nodes can usually be characterized by multiple criteria which are mutually conflicting. How to combine these multiple criteria and design an optimum cluster-based routing protocol is still a challenge to be solved. In this paper, we propose a novel joint optimization uneven cluster-based routing protocol using an integrated FCNP-VWA-ELECTRE in the whole process of the cluster-route establishment phase. This protocol operates in a cluster-route establishment phase and a data gathering phase. In the cluster-route establishment phase, FCNP-VWA allocates the relative weights to 6 criteria, and based on these weights, ELECTRE selects the CH node, enlists the CM nodes in a proper CH node and selects the next hop CH node for inter-cluster communication. The extensive simulation results show that the proposed protocol is superior to the existing schemes in terms of network lifetime.
