Abstract:

The wireless sensor network routing algorithm based on geographical position only focuses on the geographic
information. We propose a multi-path routing algorithm based on energy of nodes. We use geographic location
and energy to establish a 3D coordinate system and calculate the probability of the next hop according to the
effective forward distance and the energy of neighbor nodes. The energy consumption is scattered in the
neighbor nodes which are effective to move forward so the network survival time is prolonged. Routing holes
are reduced and delayed. Experimental results show that the number of dead nodes, surviving nodes and routing
holes are significantly improved in comparison with the two-phase geographic greedy forwarding (TPGF)
algorithm. The validity of the algorithm is verified.
