A wireless broadband ad-hoc ATM local-area network
We describe the theory, design and ongoing prototyping of a wireless ATM LAN/PBX capable of supporting mobile users with multi-Mb/s access rates and multi-Gb/s aggregate capacities. Our proposed LAN consists of network nodes called Portable Base Stations (PBS) providing microcell coverage. The PBSs are designed to be low-cost, compact and high-speed and can be relocated conveniently. We employ ...
متن کاملPerformance Evaluation of Six Wireless Ad Hoc Network Routing Protocols
Mobile wireless ad hoc networks are important for its applications in military actions and emergency rescue operations. These networks also have a high potential in commercial usage and daily life activities. One major issue for these networks is its performance. Although different attempts have been made for various routing protocols, the performance of the protocols are still relatively low c...
متن کاملPerformance Evaluation and Improvement of an Ad Hoc Wireless Network
An ad hoc wireless network is a self-organized network system. In this system, wireless terminals autonomously construct a multihop network which maintains its structural information by exchanging network information with some neighbor terminals. In such a network, the network topology changes frequently due to an unsettled wireless environment. Flexible Radio Network (FRN), one of the products...
متن کاملA Hidden Node Aware Network Allocation Vector Management System for Multi-hop Wireless Ad hoc Networks
Many performance evaluations for IEEE 802.11distributed coordination function (DCF) have been previouslyreported in the literature. Some of them have clearly indicatedthat 802.11 MAC protocol has poor performance in multi-hopwireless ad hoc networks due to exposed and hidden nodeproblems. Although RTS/CTS transmission scheme mitigatesthese phenomena, it has not been successful in thoroughlyomit...
متن کاملPerformance improvements of integrating ad hoc operations into infrastructure IEEE 802.11 wireless local area networks
In the infrastructure configuration, the standard IEEE 802.11 wireless LAN employs an access point (AP) to forward all packets regardless of their destinations, resulting in significant system performance degradation in terms of throughput and packet delay when a significant portion of packets have intra-cell destinations. These intra-cell packets could be more efficiently delivered to the dest...
