Simulating study on RHCRP protocol in utility tunnel WSN

Utility tunnel is one of the important infrastructures for the planning and building of smart city. It is of great significance to improve the efficiency of maintenance and overhaul of urban pipelines. Based on the disadvantages of the design of utility tunnel pipelines and the properties of traditional Wireless Sensors Network (WSN) protocols, the remote hybrid clustering routing protocol (RHCRP) was proposed. This protocol improved the nodes layout and cluster head (CH) election to adapt to the pipeline requirements. By comparing with traditional WSNs (low-energy adaptive clustering hierarchy algorithm (LEACH) and stable election protocol (SEP), etc.), RHCRP effectively prolonged the WSN lifetime by 50% compared with LEACH. RHCRP also to increase the cluster head quantities by 110.8% to LEACH and 57.6% to SEP, respectively. The proposed method is promising in utility tunnel WSN applications.
