It is also a good area for thesis and research on WSN security.
Routing in WSNRouting is required for effective communication between the nodes.
There are different data aggregation techniques according to the requirements.
Different algorithms employed for data aggregation include LEACH, TAG, Directed diffusion.
Advances in Wireless Sensor Network (WSN) have provided the availability of small and low-cost sensors with the capability of sensing various types of physical and environmental conditions, data processing, and wireless communication.
Since WSN protocols are application specific, the focus has been given to the routing protocols that might differ depending on the application and network architecture.In WSN, there are different parameters for clustering which are: Data Aggregation It is another good area for the thesis on wireless sensor network.Data aggregation is required to process the raw data.A malicious message can be injected into the network.An attacker can attack the physical layer of the network. The main security requirements in the network termed as CIA are: The different methods of security in WSN include Symmetric Encryption, Asymmetric Encryption, Hash Function, Digital Signature.The different techniques for data aggregation include: Data aggregation is an important concept in WSN as it not only improve energy efficiency but also reduce redundancy of data.WSN Security Security is a major issue in wireless sensor network as it is prone to outside attacks.With clustering, energy efficiency and scalability of the network can be achieved.A cluster includes a Cluster Head and the member nodes.The main aim of data aggregation in WSN is to cut down the power consumption.Not only this, it also improves the energy utilization and bandwidth in WSN.
