Design and application of sink node for wireless sensor network

Question No#1
Which problem is addressed in this paper?
In wireless sensor network the main problem is how to improve energy efficiency of nodes.

In This paper design of sink node is proposed this node can be responsible for transmission of data or instruction between sensor node and data. So it is proved in this experiment that the design of sink node is appropriate and consistent in observing environmental elements.

Question No#2
Discuss other solution of this problem given in other papers?
A flexible clustering mechanism “autonomous clustering and message passing (ACMP)” protocol is used for increasing energy efficiency in wireless sensor networks. In ACMP
Sensor nodes make clusters and dynamically choose a analogous cluster head (CH) to transfer the collected information.

Sensor nodes form clusters and use minimum energy to exchange messages.
It is proved by Simulation results that ACMP can attain a highly energy saving effect. Autonomous clustering and message passing (ACMP) protocol is used for conserving energy in wireless sensor networks.

Sensor network life time can be increased by using an effective traffic balance scheme.
ACMP gives the load distribution scheme by preserving the remaining energy to increase the life time of network.

To avoid a node runs out of its energy ACMP gives a local re-clustering mechanism.
From Experimental results it is shown that ACMP can preserve energy for lifetime of nodes.

For reporting events a new, energy-efficient system is proposed. According to this scheme
nodes that sense a certain event will combine themselves to make a cluster
cluster head is selected that will gather data from the cluster members
Forward that data to the mobile sink.

for this scheme, a new sensor node model was introduced
Network layer from scratch holds the state process model of the algorithm this layer was made by using a high-fidelity process modeling methodology.

From Simulation results it is proved that message delivery ratio is increased and a highly energy saving effect is achieved. The main objective is to save energy of sensor nodes as much as possible.
maximum data aggregation
Question No#3
Discuss other solution comparison with first paper solution?
1st paper ….. …..

sink node design is proposed consist of three parts
the power module
the storage/display module
The communication module.

different techniques such as Zigbee, Ethernet and GPRS are used on ARM7 microcontroller.
(ACMP) protocol is used for increasing energy efficiency in wireless sensor networks.

According to ACMP sensor nodes can cluster themselves and choose a cluster head (CH) to transfer information. Nodes will establish themselves into a cluster that detect an event
Select a cluster head that will gather data from the cluster members.

Question No#4
My point of view about solution of above problem? I think the solution given in first paper(Design and application of sink node for wireless sensor network) in this solution a design of sink node is given by using which energy consumption in wireless sensor network is very low so according to my point of view this is good idea.
