Design of optimal relay location in two-hop cellular systems
Relay stations are usually used to enhance the signal strength for the users near cell boundary, thereby extending the cell coverage. However, transmission through a relay station needs two transmission phases. The first phase is from base station to relay station, and the second one is from relay station to mobile station. Thus, using relay station may decrease system capacity due to two-phase...
متن کاملOptimal Capacity Relay Node Placement in a Multi-hop Wireless Network on a Line
We use information theoretic achievable rate formulas for the multi-relay channel to study the problem of optimal placement of relay nodes along the straight line joining a source node and a sink node. The achievable rate formulas that we use are for full-duplex radios at the relays and decodeand-forward relaying. For the single relay case, and individual power constraints at the source node an...
متن کاملRelay Placement for Two-Connectivity
Motivated by applications to wireless sensor networks, we study the following problem. We are given a set S of wireless sensor nodes, given as a multiset of points in a normed space. We must place a minimum-size (multi)set Q of wireless relay nodes in the normed space such that the unit-disk graph induced by Q ∪ S is two-connected. The unit-disk graph of a set of points has an edge between two ...
متن کاملOptimal placement of communications relay nodes
We consider a constrained optimization problem with mixed integer and real variables. It models optimal placement of communications relay nodes in the presence of obstacles. This problem is widely encountered, for instance, in robotics, where it is required to survey some target located in one point and convey the gathered information back to a base station located in another point. One or more...
متن کاملOptimal Relay Node Selection in Two-Hop Routing for Intermittently Connected MANETs
Recently, many researchers have been attracted to intermittently connected mobile ad-hoc networks (MANETs), which are a type of DTN (delay/disruption/disconnect tolerant network). To achieve end-to-end communication between a source node and a destination node in the networks, storecarry-forward routing has been considered as a promising solution. In this paper, we propose an algorithm for opti...
