Energy Efficiency of Geographic Opportunistic Routing
Kai Zeng, Wenjing Lou, Ming Li · 2011
This chapter proposes an energy-efficient geographic opportunistic routing (EGOR) framework, which is based on opportunistic routing but more judiciously selects a subset of the available next-hop neighbors as the forwarding candidates to strike a good balance between the packet advancement and energy cost. The performance of EGOR is justified through extensive simulations and comparisons with those of the existing geographic routing and opportunistic routing schemes. The simulation results show that EGOR strikes a good balance between energy consumption and routing efficiency in terms of Expected Packet Advancement (EPA). The chapter formulates the EGOR problem and proposes two efficient localized candidate selection algorithms. It presents EGOR scheme and its simulation results.
