Energy-Efficient Protocol for Cooperative Networks
Energy-Efficient
Protocol for Cooperative Networks
Abstract:
In cooperative networks, transmitting and receiving nodes recruit
neighboring nodes to assist in communication. We model a cooperative
transmission link in wireless networks as a transmitter cluster and a receiver
cluster. We then propose a
Cooperative communication protocol for establishment of these clusters
and for cooperative transmission of data. We derive the upper bound of the
capacity of the protocol, and we analyze the end-to-end robustness of the
protocol to data-packet loss, along with the tradeoff between energy
consumption and error rate. The analysis results are used to compare the energy
savings and the end-to-end robustness of our protocol with two non-cooperative
schemes, as well as to another cooperative protocol published in the technical
literature. The comparison results show that, when nodes are positioned on a
grid, there is a reduction in the probability of packet delivery failure by two
orders of magnitude for the values of parameters considered. Up to 80% in
energy savings can be achieved for a grid topology, while for random node
placement our cooperative protocol can save up to 40% in energy consumption
relative to the other protocols. The reduction in error rate and the energy
savings translate into increased lifetime of cooperative sensor networks.
Existing System:
·
In the
existing system we model a cooperative transmission link in wireless networks
as a transmitter cluster and a receiver cluster. But we don’t have any communication protocol for
establishment of clusters and for cooperative transmission of data.
·
In the
existing system cooperative transmission, multiple nodes
simultaneously receive, decode, and retransmit data packets.
·
Analyzation is
not available for end-to-end robustness of the protocol to data packet loss
along with the trade off energy consumption and error rate.
·
In the
existing system WIRELESS sensor networks, nodes have
limited energy resources and, consequently, protocols designed for sensor
networks should be energy-efficient.
Proposed System:
·
In the
proposed system we evaluated the performance of cooperative transmission, where
nodes in a sending cluster are synchronized to communicate a packet to nodes in
a receiving cluster.
·
The increased power of the received
signal, vis-à-vis the traditional single-node-to-single-node communication,
leads to overall saving in network energy and to end-to-end robustness to data
loss.
·
We proposed an energy-efficient
cooperative protocol, and we analyzed the robustness of the protocol to data
packet loss.
·
Our study also analyzed the capacity
upper bound of our protocol, showing improvement over the corresponding values
of the other three protocols.
·
In the proposed system simulation
results show that our cooperative transmission protocol saves up to 20% of
energy compared to the CAN protocol and up to 40% of energy compared with the other schemes.
·
Our protocol also supports larger
capacity and lower delay under high-load conditions, as compared to the CAN
protocol.
