Abstract:
Finding the minimum power route in a wireless
network is a crucial issue to be addressed. In this paper,
Wireless broadcast advantage (WBA) and wireless cooperative
advantage (WCA) are exploited separately and jointly for
finding a cooperative route in a wireless network with minimum
energy consumption considering practical coding and
modulation schemes. It assumed that a multi-hop wireless
network consisting of nodes with Omni-directional are capable
of adjusting their transmit power. For a given route subject to a
desired end-to-end throughput and outage probability
constraints an optimization problem is formulated so as to
allocate minimum sum power. During the resource allocation
exploiting WBA and WCA are taken into account separately
and together. Then after, optimal and suboptimal route selection
is done using a classical Dijkstra’s algorithm. Turbo codes with
iterative decoding algorithms are implemented with various
QAM modulation schemes.
