ICZP: an Independent Circular Zones Protocol for Heterogeneous Wireless Sensor Networks (HWSNs)

Wireless sensor networks are typically characterized by a large number of nodes. They have two main purposes. The first is to detect data from a monitoring area; the second is to send the collected data to the base station or a receiving node. Since the nodes are battery-powered, most of the proposed protocols focus on how to extend the lifetime of the network, taking into account the different constraints surrounding this type of network. In this paper, we have proposed an Independent Circular Zones Protocol (ICZP) in a network composed of multiple circular zones. Each zone is represented by a radius and many nodes that share the same amount of energy. The zones differ from each other in the length of the radius, the number of nodes and the initial energy of the nodes. Our protocol treats each zone as an independent network. The zones are responsible for collecting and transmitting data. The nodes are grouped into clusters. The members of the clusters send the collected data to the selected cluster head, which then sends it directly to the base station. As proof of concept, we compared the performance of our protocol with the SEP, Z-SEP and EEZC protocols. The simulation results prove that the ICZP outperforms these protocols in terms of stability period, first and last dead node and network lifetime.
