The energy efficiency and balancing energy dissipation are important issues for the data gather schemes in WSNs. In this paper, we propose Grid-PEGASIS to improve the performance of chain-based scheme on these two issues. The proposed Grid-PEGASIS divides the sensing area into several small Grid areas to reduce the hop variance of a sensing area chain. With the smallest hop variance, Grid-PEGASIS balances the energy consumption for nodes. Approximated analysis and simulation results show that the Grid-PEGASIS can largely prolong the network lifetimes of the first 1%, 5% and 25% nodes running out of energy.
