In this paper, the authors address the issue of network broadcasting using alternating concurrent cooperative transmissions for sensor-based wireless networks that are very lossy. The Medium Access Control (MAC)-free broadcast strategy is a simple, energy-efficient, low-overhead form of cooperative diversity-based strategy called the Opportunistic Large Arrays (OLAs), and uses a received power-based threshold to define mutually exclusive sets of nodes during the initial broadcast, such that the union of the sets includes all the nodes in the network or cooperative route. This eliminates the formation of undesirable network coverage holes, a result of the \"Dead\" nodes resulting from repeated usage.
