A Novel Strategy for High Throughput in Ad Hoc Networks Using Potential Transmission Count (PTC) Metric
A multi-hop wireless network is a network of computers and devices (nodes) which are connected by wireless communication links. The links are most often implemented with digital packet radios. Because each radio link has a limited communications range, many pairs of nodes cannot communicate directly, and must forward data to each other via one or more cooperating intermediate nodes. The PTC of a route is the total number of packet transmissions and retransmissions required to send a packet across the route, assuming that each link in the route retransmits the packet until it is successfully received across the link. PTC is designed for links with link-layer ACKnowledgments (ACKs) and retransmissions, as provided by IEEE 802.11 radios.
