Throughput enhancement based on optimum transmission range in MANETs

An analytical method is presented for finding the optimum transmission range in finite tactical mobile ad hoc networks(MANETs). The results are particularly useful for the operation of military networks, as the transmission range affects throughput, delay, and interference. Plus, the proposed method allows the optimum transmission range to be determined in advance when deploying combatants with mobile terminals. In contrast to previous studies that have focused on asymptotic approaches and calculating the connectivity probability, the proposed method obtains the optimum transmission range in a MANET based on considering both the number of mobile nodes and the operational range. Using the optimum transmission range increases the total ad-hoc network throughput by maximizing the spatial reuse of the frequency resources. It also decreases unnecessary wireless interference and improves the communication quality.
