Power efficient routing protocol for wireless cooperative sensor networks
[attachment=57637]
Abstract
A new distributed cooperative routing protocol that realizes minimum power transmission for each composed cooperative link, given the link BER (Bit Error Rate) constrained at a certain target level. The key contribution of the proposed scheme is to bring the performance gain of cooperative diversity from the physical layer up to the networking layer. Specifically, the proposed algorithm selects the best relays with minimum power consumption in distributed manner, and then forms cooperative links for establishing a route with appropriate error performance from a source to a destination node. Analytical results are developed to show that our cooperative transmission strategy achieves average energy saving of 82.43% compared to direct transmission, and of 21.22% compared to the existing minimum power cooperation strategy. The upper bound of the capacity of the protocol, and 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. The distributed and power efficient cooperative routing algorithm, which constructs the minimum power route with a small number of hops.
Introduction.
The term wireless has become a generic and all-encompassing word used to describe communications in which electromagnetic waves to carry a signal over part or the entire communication path. Wireless technology can able to reach virtually every location on the surface of the earth. Ad- hoc and Sensor Networks are one of the parts of the wireless communication. In wireless sensor network data are requested depending upon certain physical quantity. So, wireless sensor network is data centric.
Energy Minimization
A new Cooperative MAC Protocol that realizes minimum power transmission for each composed cooperative link, given the link BER constrained at a certain target level. The key contribution of the proposed scheme is to bring the performance gain of collaborative diversity from the physical layer up to the networking layer. Specifically, the proposed algorithm selects the best relays with minimum power consumption in distributed manner, and then forms cooperative links for establishing a route with appropriate error performance from a source to a destination node. From the simulation results, the total power consumption of proposed routing algorithm can reduce by a couple dB compared to the existing collaborative routing algorithms and plot the capacity of all protocols versus the load in the network. At a small load, the delay needed to recruit the collaborative nodes affects the capacity of collaborative protocol. As the load increases, the interference increases, and the number of concurrent transmissions on the different paths diminishes. The one-path scheme is not resilient to packet loss, and the maximum carried load is affected by the packet loss rate.

In the node parameter the nodes will be created. First, Nodes are positioned on a grid format .The nodes are placed in random manner. The nodes are randomly placed by using the Random manner algorithm. In, the model of cooperative transmission, every node on the path from the source node to the destination node becomes a cluster head
To determine the capacity upper bound for one hop, divide the number of data bits in the data packet transmitted in one hop by the minimum delay needed to complete this transmission.
Conclusion.
This paper proposed a cooperative MAC protocol and it analyzed the robustness of the protocol to data packet loss. When nodes are positioned on a grid, the energy savings of our cooperative MAC protocol is high compare to the Cooperative Transmission Protocol Thus the cluster was formed and analyzed power consumption using NS2 simulator. The main difference between the cooperative MAC protocol and the existing protocol is power efficient mechanism. Power efficient mechanism is used to achieve the energy level high compare to other protocol. Above 80% had achieved by using CMAC protocol
