“…Moreover, the M2M communication is maturing to enhance the network's energy and spectral efficiency through a large number of devices with shorter communication links [3,4]. Therefore, these networks have been the key area of research for the last few years [5][6][7][8][9]. In addition, the design of medium access control (MAC) protocol for these distributed wireless networks is a crucial element for their transmission handling capacity owing to the randomly distributed transceivers with simultaneous transmissions in the same frequency channel [5,[10][11][12][13].…”

“…Consequently, M2M communication technology is improving to enhance the energy efficiency, spatial reuse, and spectral efficiency by utilizing smaller transmitterreceiver (Tx-Rx) separations with a large number of devices [3,4]. On top of that, the model of the medium access control (MAC) protocol for these distributed networks is a critical factor for their transmission handling ability owing to the arbitrarily dispersed transceivers with coincident transmissions in the spatial proximity as well as at the same frequency [5][6][7]. The nature of M2M communication requires the MAC protocol to be enforced in an uncomplicated yet effective way that is actually resilient against outages due to nearby interferers.…”

An efficient scheduling strategy guarantees the simultaneous transmission and successful reception by the scheduled nodes even inside a congested wireless ad hoc network. Owing to the dispersed nature of ad hoc networks, the node packing algorithm needs to be implementable without having network-wide channel state information and should additionally be able to pack the optimum number of successful transmissions. The proposed algorithm, for a network with nonhomogeneously distributed nodes, makes the decision to either inhibit or permit an active interferer around an active receiver based on the interferer's transmission power. The analysis evidenced that the suggested scheme provides an estimated 100 times superior transmission capacity when equated to the random aloha scheme. Moreover, the proposed strategy proved its vitality by demonstrating substantial improvement in transmission and transport capacity in comparison to the preexisting renowned scheduling schemes for distributed networks. The final results present a closed-form formula for the best possible exclusion-zone size multiplier factor in terms of the network parameters, i.e. the network's path-loss exponent, spreading gain, SINR threshold, outage constraint, and Tx-Rx separation.
