Not only this, it also improves the energy utilization and bandwidth in WSN. You can work on the different load balancing strategies for your Ph. It is also a good topic for the thesis on WSN. The main security requirements in the network termed as CIA are: Since all the nodes are safe and there is no scope of any attack by the intruder, so packet delivery ratio is also very high in detection-based path hopping.
It is a very challenging process in wireless sensor network due to different design issues and characteristics. The protocol divides the network into different clusters of sensors to reduce the amount of data.
In response to that message, all the nodes will reply to the master node. In the authentication reply they will send their network id and a Network key to master node. But these paths are not secure because there contain some malicious nodes also. Data aggregation is required to process the raw data.
Distance vector is method to calculate distance between two points in two dimension plane. A malicious message can be injected into the network. This reduces the packet-loss during transmission and thereby results in increasing the packet-delivery ratio.
It is a dynamic and cost-effective area of networking suitable for high-bandwidth and dynamic applications. The different techniques for data aggregation include: To make the WSN more effective, a large number of nodes are required.
Intra-clustering routing Data Aggregation It is another good area for the thesis on wireless sensor network. About this resource This Information Technology essay was submitted to us by a student in order to help you with your studies.
It is the process of finding a suitable path for data transmission from source to the destination. Delay in routing 3. Let suppose there are two points p1 and p2 having coordinates x1, y1 and x2, y2 respectively.
Simulation of the WSN with errors, without errors, original path hopping and detection-based path hopping techniques are displayed to explain the advantage of detection based path hopping in WSNs.
This value of d will decide the next intermediate in the path. If the node with shortest path is an authenticated node then the sender will send data to that node otherwise if next node is a malicious node than the sender will check node with less distance and same procedure will be performed until an authenticated node will not be found.
In this type of attack, a wrong path is advertised by a malicious node during the route finding process. Hence, using this technique makes the network more secure than the other existing path hopping techniques.
Network Security Network Security includes a set of policies and activities designed to protect the integrity of the network and its associated data. In a single black hole attack, an individual malicious behaves as the black hole node.
Similarly this process will work on all the intermediate nodes until the next receiving node.
In the scenario, the sensor nodes are represented by the blue colour. The lines are giving the impact of the various paths through which the master node is broadcasting the single key over the network in order to check for the authenticated nodes.
Various restaurants and hotels provide WLAN hotspots to access the internet. The sender will first calculate the shortest path to the neighbour in the direction to the receiver. Its applications can also be found in homes, schools, colleges, and offices. In this phase data transmission will take place between nodes.
The main aim of data aggregation in WSN is to cut down the power consumption. This differentiation helps in choosing the right and accurate path between the sender and the receiver which consists of authenticated nodes only. In a cooperative black hole, a group of nodes acts as the black hole nodes.
In the second phase, detection procedure is followed to identify the authenticated nodes.
Here, we have discussed briefly some most common attacks and the techniques generated to recover them.Wireless sensor networks (WSNs), as distributed networks of sensors with the ability to sense, process and communicate, have been increasingly used in various fields including engineering, health and environment, to intelligently monitor remote locations at low cost.
