摘要：There is a tradeoff between routing efficiency and
energy equilibrium for sensor nodes in wireless sensor networks
(WSNs). Inspired by the large and single-celled amoeboid
organism, slime mold Physarum polycephalum, this paper
presents a novel Physarum-inspired routing protocol (P-iRP) for
WSNs to address the above issue. In P-iRP, a sensor node can choose
the proper next hop by using a proposed Physarum-inspired
selecting next hop model (P-iSNH), which comprehensively considers
the distance, energy residue, and location of the next hop.
As a result, the P-iRP can get a rather low algorithm complexity
of , which greatly reduces the processing delay and saves
the energy of sensors. Moreover, by theoretical analysis, the
P-iSNH always has an equilibrium solution for multiple next
hop candidates, which is vital factor to the stability of routing
protocol. Finally, simulation results show that P-iRP can perform
better in many scenarios and achieve the effective tradeoff
between routing efficiency and energy equilibrium compared to
other famous algorithms.
