11. Summary of the new findings of the thesis:

I improved a clustering routing protocol base on choosing CH node, which considers energy residual and the distance of candidate node to BS. The improved protocol can work well on homogeneous wireless sensor network. According to the algorithm, each candidate node, which want to become CH at the round i need to have the energy residual higher than the remaining average energy level of all nodes alive and consider the distance from it to BS node.

I proposed a new cluster chain-based scheme for energy efficiency, called "Sector Clustering Chain-Based Routing Protocol" (SCBC) for heterogeneous wireless sensor networks, where the node is different battery capacity but the same processor, memory and transmission. According to this scheme, entire the sensor network area will be divided into logic sectors (clusters), which can be balance of the number of node in each sector (assuming a BS is in the center of network area) based on calculating the angle of node and BS with OXY coordinate system. Furthermore, the algorithms are adjusted interval stability time to transmit data in each round to reduce the cost of rebuilding the cluster.

I propose a new routing chain based scheme combined with aggregating and compressing data for better energy efficiency, called "Data Fusion and Chain-Based Clustering for Energy-Efficient Routing Protocol in WSNs" (DFCBC). All nodes in the network are connected together into a long chain to reduce the communication distance between nodes. In addition, the data will be fused and compressed by using distributed source code to reduce communication costs before transmission.

I propose a new routing algorithm based on building the minimum spanning tree, which is associated with aggregating and compressing on tree and sleep schedule, titled "Data Fusion and Tree-Based Clustering Routing Protocol for Energy-Efficient in Wireless sensor networks -(DFTBC)" and "Sleep Schedule and Tree-Based Clustering Routing Protocol for Wireless sensor networks -(SSTBC)" for energy efficient. The simulation results show that the proposed algorithm is energy efficiency better than available protocols about using energy.
