On Relay-assisted Cellular Networks
Cellular operators are developing low-cost relays to improve the coverage and capacity of next generation cellular networks. Deploying low cost relays reduces the infrastructure cost of setting up new base stations in order to support the rapidly growing number of subscribers. In this thesis, we present methods to design the system architecture and efficient protocols to achieve maximum benefit...
متن کاملRelay-Assisted Scheduling in Cellular Networks with Hybrid-ARQ
This paper studies the problem of relay-assisted user scheduling for downlink wireless transmission. The transmitting base station employs hybrid automatic-repeat-request (ARQ) transmission with the possible assistance of a set of fixed relays to serve a set of mobile users. By minimizing a cost function that depends on the queue lengths at the base station and the number of retransmissions of ...
متن کاملRelay Routing and Scheduling for Capacity Improvement in Cellular WLANs
In classical infrastructure-based wireless systems, all mobile terminals communicate directly with the access point. In such systems, the transmission capacity, i.e., the amount of traffic successfully communicated to/from the access point, is important. This paper studies the possibility to increase this capacity by using mobile terminals as intermediate relays. These relays reduce the communi...
متن کاملConsistent Sensor, Relay, and Link Selection in Wireless Sensor Networks
In wireless sensor networks, where energy is scarce, it is inefficient to have all nodes active because they consume a non-negligible amount of battery. In this paper we consider the problem of jointly selecting sensors, relays and links in a wireless sensor network where the active sensors need to communicate their measurements to one or multiple access points. Information messages are routed ...
