The number of subscribers in Wireless Networks such as Wireless in Local Loop (WiLL) is increasing, thereby it becomes beneficial to use spectrum reusability techniques. To improve the capability of WiLL systems, multi-hop relaying is used. In the existing WiLL system, number of subscribers that can be simultaneously served is limited, with increase in subscriber density. It is to develop Throughput Enhanced Wireless in Local Loop (TWiLL) architecture that uses multihop relaying and shortcut relaying to reuse bandwidth of the system. The technological challenges faced by the existing system are its performance output obtained by analyzing the Packet Acceptance Ratio vs Mean Call Holding Time and Packet Acceptance Ratio vs Mean Inter Call Arrival Time of existing TWiLL system is less as compared to that of the proposed TWiLL system. The current work done focuses on designing a TWiLL system with a Packet Acceptance Ratio vs Mean Call Holding Time of 0.9 (increase in 0.5) and Packet Acceptance Ratio vs Mean Inter Call Arrival Time of 0.9 (increase in 0.4).
