摘要:Network wide communication is an essential criterion for all wireless sensor networks, to transmit the collected data from environment to base station (sink node) in an efficient way. The wide network coverage is provided by constructing Mobile Backbone Networks (MBN), which are dynamic networks. These networks have two types of nodes. They are Mobile backbone nodes and Regular nodes. The Mobile backbone nodes have superior mobility and communication capability than regular nodes. All the information needs to be routed through mobile backbone nodes to regular nodes. The communication between clusters is done through backbone node so that transmission overhead is less. In this paper, we are mainly concentrates on thr oughput optimization and assigning new regular nodes. First the throughput range is calculated for each cluster, and then data packets are transmitted in such a way that the calculated range of throughput for each cluster is satisfied. The number of regular nodes that can be successfully assigned to mobile backbone nodes can be improved by means of adopting network design formulation technique. In case of any failure of mobile backbone node ,new cluster head is elected based on high energy first (HEF) algorithm, where the residual energy of the nodes are considered for election
