Efficient Path Finding Algorithm for Transmission of Data in Agricultural Field Using Wireless Sensor Network

Transmission of data from the source to the sink requires an efficient path so that the network life is enhanced. Longer shelf life for battery is essential when it is difficult to replace the battery too often as in agricultural field. To achieve this, in this paper we have proposed an algorithm to find the efficient path between the sink (base station) and the source so that the network can be alive for one cropping season.

Energy aware path search for sensor with parameters as used in Agricultural field

One of the important issues in wireless networks is the Routing problem that is effective on system performance, in this article the attempt is made to propose a routing algorithm using the bee colony in order to reduce energy consumption in wireless relay networks. In EBCD algorithm, through combined of energy, distance and traffic parameters a routing algorithm for wireless networks is presented with more efficiency than its predecessor. Applying the bee colony method would allow the placement of the parameters under conventional conditions and to get closer to a mechanism with a better adaptability than that of the existing algorithm. According to the parameters considered, the proposed algorithm provides a fitness function that can be applied as a multi-hop. Unlike other algorithms of its kind this can increase service quality based on environmental conditions through its multiple services. This new method can store the energy accumulated in the nodes and reduce the hop restrictions.Sensors placed in agricultural field should have long network life. Failure of node or link allows rerouting and establishing a new path from the source to the sink. In this paper, a new path is established such that it is energy aware during path discovery and is active for longer interval of time once it is established. The parameters used for simulation are as those used in agricultural application.

Uniform distribution of energy in wireless sensor network using efficient path search

Wireless Sensor Network has constraint with energy and computation. Network Life is based on the way the energy in the battery is used. Continuously sending data along a specific path for long intervals of time, results in large amount of energy consumption. This could eventually lead to network partitioning, which in turn will create a path loss between the sender and receiver. Though several (sensor) node with sufficient energy might exists, delivery of data to the destination node might not be possible. Changing path often can be solution. But question remains, how often? New routing protocol called U_AODV is proposed, so that there is a uniform energy distribution and a possible path between the source and the destination as long as possible.

Aggregation using the concept of Dynamic-Sized Data Packet for Effective Energy Saving in Wireless Sensor Network

Data aggregation process can extract relevant information from raw data obtained from various sources using certain mathematical functions. Aggregation reduces the transmission of redundant data. A protocol named DP_AODV is implemented in this paper. Aggregator nodes (cluster head) are identified using the positional information. Routes are established between these aggregator nodes using efficient routing techniques. Data is aggregated along the path to the destination conserving additional energy. The aggregation process involves averaging the data if it is within the threshold range, else, only the data part along with the positional information is appended to the payload. Size of the Data packet varies dynamically based on the number of nodes having co-related data at that particular instance. The common header occupies a substantial part of the packet. Avoiding multiple transmission of common part of the header saves energy.

IN-NETWORK AGGREGATION USING EFFICIENT ROUTING TECHNIQUES FOR EVENT DRIVEN SENSOR NETWORK

Sensors used in applications such as agriculture, weather, etc., monitoring physical parameters like soil moisture, temperature, humidity, will have to sustain their battery power for long intervals of time. In order to accomplish this, parameter which assists in reducing the consumption of power from battery need to be attended to. One of the factors affecting the consumption of energy is transmit and receive power. This energy consumption can be reduced by avoiding unnecessary transmission and reception. Efficient routing techniques and incorporating aggregation whenever possible can save considerable amount of energy. Aggregation reduces repeated transmission of relative values and also reduces lot of computation at the base station. In this paper, the benefits of aggregation over direct transmission in saving the amount of energy consumed is discussed. Routing techniques which assist aggregation are incorporated. Aspects like transmission of average value of sensed data around an area of the network, minimum value in the whole of the network, triggering of event when there is low battery are assimilated.
