An Even Cluster-Based Routing Protocol for Wireless Sensor Networks

Research and design on clustering routing has been the focus of the wireless sensor network routing protocols. Based on the even clustering routing GRID,we propose a new routing protocal named Q-GRID. In Q-GRID,the network coverage area is quad-tree divided and coded. The improvement of GRID is based on residual energy and transmission distance between cluster head,improving the strategy of selecting cluster head and proposing a better one. Based on residual energy and transmission distance when a next hop node is selected,the energy dissipation of whole network is more even. Both of the algorithms were emulated in OMNeT ++. The result of the emulation proves that compared with GRID,Q-GIRD lifetime is longer and the energy dissipation is less.
