摘要：Wireless sensor network, consists of sensor nodes in capacity of hundred or thousand, which deployed in a particular manner. The goal of these sensor nodes is to capture the environmental data and send it to sink node. Various nodes deployment strategies like square, triangle, hex grid have been proposed. In this paper minimum numbers of sensor nodes are used to cover the specified geographical area using hex grid deployment. The study shows that the deployment of nodes in a hex grid manner is the best deployment to cover the maximum area by using the minimum number of nodes. In this pape r a hex grid based multi hopping routing scheme is proposed. This scheme minimizes the data transmission delay as well as improves the reliability of minimally connected network. The simulation result shows that the performance of the proposed scheme is better when sink positioned in the middle of the network.
