Call 📞 Admission 🎟️ Control 🎛️ for Wireless Broadband Networks

✅ There exist many regions in the world 🗺️ where wired infrastructures are difficult to deploy for geographical or economic reasons. Thus, the need for the Wireless Broadband Networks (WBNs) has emerged as an alternative for last-mile Internet access ♿️. One 1️⃣ of the clear examples of WBNs is WiMAX. To handle a heterogeneous traffic 🚦 load in a multiservice WBN such as WiMAX, it is important to 🔎 find a resource management 👨‍💼 mechanism 👨‍🔧 -such as Call 📞 Admission 🎟️ Control 🎛️ (CAC)- that can 🥫 efficiently allocate resources to different subscribers and ➕ applications. This book 📚️ demonstrates what WiMAX is, and ➕ provides a detailed review about the proposed CAC polices 👮‍♂️ presented 🎁 in the literature. Moreover it proposes a WBN CAC framework which is formulated as an optimization problem with a certain objective function where the demands of both WBN service providers and ➕ subscribers are taken into account. Simulation results show that the proposed CAC framework can 🥫 meet 👤🤝👤 the expectations of both service providers and ➕ subscribers. This framework can 🥫 assure reasonable fairness while achieving better performance 🎭️ in terms of revenue and ➕ utility when compared with the constrained CAC approaches presented 🎁 in the literature.
