At a time when the Delay Tolerant Network (DTN) Research Group is making great strides in establishing the much anticipated Solar System Internet (SSI) in space, its terrestrial counterpart is not far behind. The Earth bound DTN has been dedicated to connecting remote, heterogeneous, fluctuating, mobile and undisciplined networks like sensor, military and disaster struck areas. The Homing Pigeon Based DTN (HoP-DTN), a variant of DTN, was specifically conceptualized to serve some of these networks whose characteristics are different from the general delay or disruption tolerant networks. HoP-DTN uses special message carrying nodes, pigeons, to proactively route messages around the network. As it works in areas like disaster response or military, energy conservation is imperative here. Till now providing a solution to this energy issue has been lacking in HoP-DTN. Also routing in HoP-DTN is a Traveling Salesman Problem. This paper proposes a 4-step mechanism to address both of these issues. In view of that some changes to the classical modeling of HoP-DTN has been done to accommodate the variations. The deployment area has been divided into zones with pigeons following a 4-step detailed course plan and scheduling strategy to achieve better routing and more energy efficiency. To further enhance energy efficiency we introduce a Blockchain inspired energy sharing scheme. Mathematical modeling and simulation results further affirm our proposition.
