In this paper, we propose a novel group formation scheme which is integrated with an EMGC protocol in order to cope with dynamic group change. It uses a link expiration time and residual energy to form a stable link in a group. It also has a group merging procedure to decrease the number of groups. Furthermore, we develop two additional functions for the protocol, i.e., GL rotation and a stay connection procedure to diminish energy consumption of sensor nodes in the network. Simulation results show that the proposed protocol outperforms MBC, EMGCwoh, and EMGC protocols in terms of data delivery, network lifetime, and energy dissipation per round with various group change probabilities and percentages of groups.
