Obviously, it is inefficient and pretty impossible to replace or recharge batteries of sensor nodes (SN) in a vast wireless sensor networks (WSN). Consequently, one of the major concerns in such networks is energy efficiency (EE) which helps to improve reliability and lifetime of these networks. Many researches have been conducted and some efficient methods have been introduced to increase the EE in WSNs. Low-energy adoptive clustering hierarchy (LAECH) is one of these methods, which can decrease energy consumption of each SN. This paper offers a novel technique of clustering and selecting cluster head (CH) which takes the energy level of SNs and distance between them into consideration. This algorithm improves EE and lifetime of each SN. Simulations prove this claim. Moreover, the proposed protocol has not significant complexity since there is no difficult equation to cause overload, then in term of simplicity this novel protocol is significantly efficient.
