WANG Ze-ye, CHEN Hui-jie, LI You-qi. CTP routing algorithm for wireless sensor networks based on path optimization[J]. 2016, 35(12): 122-124+128. DOI: 10.13873/J.1000-9787(2016)12-0122-03.
To address load unbalance problem which can led to high forwarding rate and short lifetime of network in wireless sensor networks( WSNs). An optimal path-based protocol based on collection tree protocol( CTP)
is proposed
which is called depth and children CTP( DC—CTP). Considering the path depth and the number of child node influence the forwarding data number in the whole network
DC—CTP optimized the path choice for every node in the network. TOSSIM simulation results show that the path which is selected by DC—CTP
can reduce the forwarding packet number of nodes about 10. 25 %
