LE-VBF: Lifetime-Extended Vector-Based Forwarding Routing

Abstract

In Underwater sensor networks (UWSN), Nodes are powered by battery. So saving energy is an important factor to estimate routing protocol. In this paper, we briefly introduced the vector-Based Forwarding and proposed an energy balance method to improve the lifetime of originate VBF. We sensor the energy information of neighbor nodes and decide whether participate in transport packets according the residual energy information of individual sensors. In case the energy of this node is overtop the average energy of his neighbor nodes, this node will transport packets. If not, the node simply drops the packet. The results show the Lifetime-Extended Vector-Based Forwarding (LE-VBF) prolonged the lifetime.
