Description: Abstract: The optimal number of cluster heads is an important parameter of wireless sensor network performance. Network nodes will consume more energy if the number of cluster heads is too much or too little. This paper focuses on novel calculation method for ptimal number of cluster heads. Base on the analysis of LEACH energy dissipation model,novel lation method is derived from the total energy dissipation of a round. Simulation shows the
relationship of the optimal number of cluster heads, the number of frames in steady state phase and the distance between cluster heads and base station (BS).And it provides a theoretical basis for calculation of optimal number of cluster heads which can reduce
the energy consumption among nodes and achieves
an improvement on the network lifetime. Platform: |

Description: The sensor nodes of a wireless grain depot
surveillance system are deployed in crystal grids, which provide
lot of valid position information. To avoid the energy
consumption unbalance of the single hop routing model adopted
by LEACH protocol, a novel hybrid routing model is proposed
in this paper. Multi-hop routing is introduced into the distant
field nodes through right angle transferring of approximate
equivalence consumption path. And the average energy
consumption is used as a threshold of selecting intermediate
transferring nodes to minimize total variance of node s energy
consumption, so that balance the whole network. Simulations
show that the hybrid model eliminates hot spots within cluster
and prolong the lifetime ofWSN. -The sensor nodes of a wireless grain depot
