An Improved Cluster Header Switch Gateway Routing Protocol

Based on cluster head gateway switch routing protocol, this paper proposed an improved Cluster head Gateway Switch Routing Protocol for the problem about heavy cluster head load and high energy consumption. In the clustering mechanism, this paper utilizes the node connectivity, the node neighbor change rate and node remaining energy as the weight influence factors to calculate the node weight. In the routing protocol, this paper proposes a hybrid routing protocol. Then this paper utilizes analytical hierarchy process to calculate the weights of the three factors and obtain the node weight. Finally, the OMNET experiment is carried out to verify the effectiveness of the improved protocol in increasing cluster stability and reducing cluster head load.
