Wireless sensor network is composed of hundreds and thousands of small wireless sensor nodes which collect information by sensing the physical environment. The sensed data is processed and communicated to other sensor nodes and finally to Base Station. So energy efficient routing to final destination called base station is ongoing current requirement in wireless sensor networks. Here in this research paper we propose a multi-hop DEEC routing scheme i.e. G-DEEC for heterogeneous networks where we deploy rechargeable intermediate nodes called gateways in-between cluster head and base station for minimizing energy consumption by sensor nodes in each processing round thereby increasing the network lifetime and stability of wireless sensor networks unlike DEEC
