Energy‐aware multipath geographic routing for detouring mode in wireless sensor networks
Haojun Huang, Guangmin Hu, Fucai Yu · European Transactions on Telecommunications · 2011
ABSTRACT For energy‐constrained wireless sensor networks, we present an Energy‐aware Multipath Geographic Routing (EMGR) protocol. EMGR utilizes geographic information, the characteristics of energy consumption and the metric of advanced energy cost to select the next forwarding node, and uses a dynamic anchor list to shift routing path for load balance. Simulation results show that EMGR is superior to other protocols in terms of energy efficiency, network lifetime, end‐to‐end delay, and packet delivery ratio. Copyright © 2011 John Wiley & Sons, Ltd.
