Abstract: Wireless sensor network (WSN) consists of a large number of sensors to sense different variations in the surroundings from various locations. These sensors communicate with each other to forward the gathered data to the base station (BS). Hence, the energy consumption is one of the main issues that affect the overall performance of the WSN implementation. In this paper, a quid pro quo LEACH (QPQ-LEACH) protocol is introduced. The working mechanism of the cluster head (CH) is maintained. However, the CH will not be replaced by new CH until it expends energy due to its continuous working time that is less than a certain threshold value. Moreover, the QPQ-LEACH trades the re-clustering process to save the energy consumed for establishing new clusters every round. The simulation results show that the proposed QPQ-LEACH protocol effectively reduces the energy consumption and prolongs the network lifetime in comparison with other known protocols.
