Abstract
Abstract In a fire rescue operation, a fast, reliable, and robust communication system is needed to quickly take control of the emergent situation. One of the most important issues in firefighter communication networks (FCNs) is the design of a specialized routing protocol that caters to the specific needs of the fire rescue application. This paper proposes a reliable, energy-balancing, multi-group (REM) routing protocol for an FCN. Since firefighters work in groups, a cluster-based hierarchical approach was adopted. REM is intended to achieve reliability and energy balancing in data communication by incorporating metric-based cluster head (CH) selection, CH rotation among cluster members, and a routing algorithm. Within a cluster, the node with highest metric value based on residual energy and number of connections is chosen as the CH. The CH’s responsibilities are rotated periodically among the cluster members. REM chooses nodes with a higher metric based on residual energy, number of connections, and number of hops to the base station (BS) as the next hop for forwarding data to the BS. This helps to achieve reliability, less delay, and energy balancing when compared with other routing schemes, as evident from the simulation results.

The REM scheme uses a metric value based on the residual energy and number of one-hop neighbors or connections of a node for cluster head (CH) selection
Summary
One of the most essential public safety activities is fire rescue. Fire rescue operations are critical because the lives of rescue workers, firefighters, and civilians depend on them. Keeping in mind the energy constraint and the reliable and timely message delivery requirements of the FCN, the proposed scheme uses the residual energy level, number of hops to the BS, and number of connections as a selection metric for the hop to forward data to the BS.
