In order to adjust the transmission power of nodes for minimizing total energy consumption in wireless sensor networks
a new distributed algorithm called ERBOP(enhanced relative neighborhood graph broadcast oriented protocol) was proposed which was an improvement upon RBOP(relative neighborhood graph broadcast oriented protocol) pre-sented by Cartigny et al.In ERBOP
a sub-graph of relative neighborhood graph
which was a sparse connected graph and contains minimum spanning tree
was locally constructed by eliminating long edges.Moreover
1-dominating connected dominating set was constructed basing on the sub-graph
and only the dominating nodes participated in the broadcasting.The simulation results show that ERBOP conserves energy efficiently.
