The Cooperative wireless network is a mean to improve the ideas of using the broadcast nature of channel wireless to make the nodes communicate and help one another. In this paper the analysis of BER of wireless cooperation networks have been used different types of fading channels to estimate the error rate performance for wireless transmission and it is suited to network with OFDM system. So we...
A signal-plus-noise (S+N) energy selection diversity combining (S+N-ESC) scheme for M-ary phase shift keying (MPSK) in Rayleigh fading channels is mathematically analyzed. Also, the S+N-ESC scheme for MPSK and 16-quadrature amplitude modulation (16-QAM) signaling in Nakagami-m and Rician fading channels is studied by computer simulations. The S+N-ESC selects the branch with the maximum S+N energy...
In this paper, the problem of energy saving in cooperative multi-hop wireless sensor networks is studied with the constraint of a given outage probability. In these networks, each node transmits its signal to the next mcoop nodes on the route ending with the sink node. Rice and Nakagami channels are considered. In this paper, we derive the upper bound of the end to end (e-2-e) outage probability for...
Distributed MIMO or Cooperative transmission is an appropriate way to use in sensor networks that have constraint on energy consumptions. In this paper, we consider a minimum end to end (e-2-e) total power allocation while satisfying an e-2-e given maximum outage probability as the constraint for a cluster-based multi-hop cooperative network. To simplify this optimization problem, we apply some approximations...
In this paper, the amount of energy saving is studied in cooperative multi-hop wireless sensor networks with the constraint of a given outage probability. In these networks, each node transmits its signal to the next m_coop nodes on the route ending with the sink node. Nakagami channels are considered. Numerical results show that the purposed cooperative routing can provide considerable energy saving...
