Energy-Efficient Adaptive Routing for Ad Hoc Networks With Time-Varying Heterogeneous Traffic

Authors propose a hybrid networking strategy for large-scale energy constrained ad hoc networks. Referred to as Energy-Aware GEolocation aided Routing (EAGER), this protocol optimally blends proactive and reactive routing strategies for energy efficiency. Specifically, EAGER partitions the network into cells and performs intracell proactive routing and inter-cell reactive routing. The cell size and transmission range are optimized analytically for energy efficiency. Furthermore, by gluing cells around the hot spots in the network, EAGER is capable of adapting to time-varying heterogenous traffic patterns.
