Abstract
In cooperative networks, to transmit and receive nodes recruit neighboring nodes to assist in communication. We establish the cluster technique for co-operative transmission of data. We then propose a cooperative communication protocol for establishment of these clusters and for cooperative transmission of data. We derive the upper bound of the capacity of the protocol, and we analyze the end-to-end robustness of the protocol to data-packet loss, along with the tradeoff between energy consumption and error rate. The analysis results are used to compare the energy savings and the end-to-end robustness of our protocol with two non-cooperative schemes, as well as to another cooperative protocol published in the technical literature. For a regular line topology, it is possible to achieve energy savings of 39%. For a grid topology, it is possible to achieve energy savings of 80%, while for random node placement our cooperative protocol can save up to 40% in energy consumption relative to the other protocols. To increase the received power at receiving node and decreasing probability for bit error and packet loss. It increased lifetime of cooperative sensor networks.
