Ad hoc networks are formed by intermediate nodes which agree to relay traffic. The link between nodes is broken when a node rejects to relay traffic. Various parameters like depreciation in the energy of a node, distance between nodes and mobility of the nodes play a vital role in determining the node's rejection to relay traffic. The objective of this paper is to propose a novel model tha...

We consider the communication problem in a multi-hop relay network where the intermediate relay nodes cannot transmit and receive at the same time. The motivation for this assumption comes from the fact that current radios operate in TDD mode when the transmitting and receiving frequencies are the same. We label such a node radio as a cheap radio and the corresponding node of the network as a c...

In multipath communications of Wireless Sensor Networks (WSNs), data packets are forwarded towards the static base station (BS) through a number of paths, using a set of relay nodes. The shortest path between a source node and the destination node does not always guarantee a stable path. In this paper, a probabilistic approach for selecting energy aware stable path in WSN is proposed by which i...

In this paper, we study the optimal cooperative beamforming problem in amplify-and-forward (AF) multi-user and multi-relay networks, which face challenges of rapid node number variations per-node power limits. To achieve extra diversity gain, direct-link (source-to-destination) distributed relay-link signals are jointly exploited. The is formulated as maximum relay transmit minimization problem...

In this paper, we propose various kinds of two-way multi-antenna relaying with simultaneous wireless information and power transfer (SWIPT) and investigate their performance. Specifically, we first consider a two-way relay network where two single-antenna end nodes communicate with each other through a multi-antenna relay node that is energy constrained. This relay node harvests energy from the...

Wireless cooperative communication technology share resources with each other, can get space diversity gain and improve the system transmission performance, so that in recent years it has received the extensive attention of many scholars in the field of wireless communications. In view of the flat fading channel, adaptive relay node selection and transmission strategy based on space time block ...
