Optimal 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...
متن کاملDesign 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 کامل[Article] Optimal Power Allocation Strategies in Two-Hop X-duplex Relay Channel
We consider a dual-hop, decode-and-forward network where the relay can operate in FD or HD mode (X-duplex relay). We model the residual self-interference as an additive Gaussian noise with variance proportional to the relay transmit power, and we assume a Gaussian input distribution at the source. Unlike previous work, we assume that the source is only aware of the transmit power distribution a...
متن کاملPerformance of ad hoc networks with two-hop relay routing and limited packet lifetime (extended version)
We consider a mobile ad hoc network consisting of three types of nodes (source, destination and relay nodes) and using the two-hop relay routing. This type of routing takes advantage of the mobility and the storage capacity of the nodes, called the relay nodes, in order to route packets between a source and a destination. Packets at relay nodes are assumed to have a limited lifetime in the netw...
متن کاملOptimal Positions of Relay Stations for Cluster-Based Two-Hop Cellular Network
Multihop cellular networks is an exciting and a fledgling area of wireless communication which offers huge potential in terms of coverage enhancement, data-rates, power reduction, and various other quality of service improvements. However, resource allocation in MCN is an NP-hard problem. Hence, significant research needs to be done in this field in order to efficiently design the radio network...
